Question 16 of 30
John is testing the effect of temperature on the solubility of sugar in water.
He plans to determine the mass of sugar dissolved in a saturated solution.
He will begin with a known mass of sugar and add sugar to water until the
solution is saturated. He will then calculate how much sugar dissolved by
subtracting the remaining mass from the initial mass.
He organized data about his experiment in the following table:
Group A
Group B
Group C
Volume of water
100 mL
Temperature
25°C
1000 g
Initial mass of
sugar
800 g
Final mass of
sugar
Which factor should be the same in all three groups?

Answers

Answer 1

Answer:

As John is testing the effect of temperature on the solubility of sugar in water. To test this, he will measure the amount of sugar dissolved at different temperature level.

Explanation:

I hope it's helpful for you ☺️
Answer 2

The volume of water should be the same in all three groups.

What is solubility?

Solubility is the property of a substance to dissolve in a solvent to form a homogeneous solution at a particular temperature and pressure.The volume of water should be the same in all three groups. This is because the experiment is testing the effect of temperature on the solubility of sugar in water, and any variation in the volume of water could affect the results.

By keeping the volume of water constant, John can ensure that any changes in the amount of sugar dissolved are solely due to changes in temperature and not changes in the amount of water. Therefore, he can compare the results of each group and draw conclusions about the effect of temperature on the solubility of sugar.

Answers

Answer:

warm: gentle long lasting rain , half red circles, slides over the top of air masses

cool: blue triangles, force existing air into atmo., heavy storms

Explanation:

Gentle, long-lasting rain, sliding over the top of existing air mass and shown as red half circles on the map was an indicator of warm fronts whereas heavy storms, forcing existing air up into the atmosphere and shown as blue triangles on the map are indicators of cold fronts.

What are warm fronts?

A warm front occurs when warm air mass overtakes colder air mass while moving forward resulting in the production of precipitation, clouds, or thunderstorms. A light rain or drizzle is also a result of warm fronts.

A cold front occurs when a cold air mass undercuts a warm air mass while moving forward. when the warm air is lifted by colder air, it causes clouds to condense resulting in thunderstorms, or even tornadoes. Severe weather accompanied by strong winds and low temperatures was created by cold fronts.

Warm fronts bring gentle, long-lasting rains, slide over the top of the existing air mass, and are shown as red half circles on the map whereas cold fronts bring heavy storms, forcing existing air up into the atmosphere, and shown as blue triangles on the map.

Therefore, warm fronts bring gentle and long-lasting rains, whereas cold fronts bring heavy storms.

What is one difference between primary and secondary succession? Primary succession can start from bare rock; secondary succession starts from organic soils. Primary succession occurs in habitats with rich organic soil; secondary succession does not. Primary succession is always caused by human disturbances; secondary succession is not. Trees are often the first colonizing species in primary succession, but trees are never the first species in secondary succession.

Answers

Answer:

Primary succession can start from bare rock; secondary succession starts from organic soils.

Explanation:

Primary succession is when the growth of pioneer species rake place in an bare and new environment. The secondary succession is when the growth of species take place due to the disturbances in the primary succession. The secondary succession is based on fire, floods, or any man-made disturbances in the region.

Magnetic fields on the sun are produced by the sun’s uneven rotation and:
A. The movement of sunspots on the sun’s surface.
B. The movement of gases in the corona.
C. Gases in the convective zone.
D. Gases in the radiation zone.

Answers

Answer:

The correct answer is - C. Gases in the convective zone.

Explanation:

The heat of the sun causes the atoms to be ionized and create a charged gas known as plasma. These gases or plasma are move in the convective zone with the uneven and rapid rotation of the sun.

This creates the electric currents due to the charge in gases which ultimately create magnetic fields. Sun's rotation causes the sun's overall magnetic field to have some degree of order and to be somewhat stable over time.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.

Which relates the wavelength and frequency of a wave?

The frequency is the number of wavelengths that pass a fixed point in a second.

A wavelength is the distance on a wave between one frequency and the next.

The time it takes for one wavelength to pass a fixed point is the frequency.

The speed at which a wavelength travels is the frequency of the wave.

Answers

Answer:

The correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.

Explanation:

The wavelength of a wave is the distance between one point on a wave and the nearest point or one crest to another crest of a wave.  The frequency of the wave is the number of wavelengths that pass a fixed point in a second.  A period is the amount of time one wavelength requires to pass a point.

Frequency = 1/wavelength, which means if one increases other decreases.

Thus, the correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.

Penny attended a four year state college. She took out a student loan to pay for her tuition and room & board for the four years she was attending the college. Her tuition fees were $6,970 per year, and the cost of her room and board was $11,320 per year. Now that she has graduated, she will have to start paying back her loan. Fortunately, Penny has a grace period of one year before she has to start paying back the loan. Her loan details are as follows: there is a fixed-rate interest of 4.5% and the interest compounds each month. During her one year grace period, interest will accrue on the loan, so that when she has to start paying the loan back she will owe more than what she owes now. Her goal is to be able to payoff the loan in 10 years. Given all of this information, answer the following questions:1. What is the original loan amount, i.e. how much were the total costs for tuition plus room & board for the four years that Penny attended the college?2.
