There are two students standing outside in direct sunlight in front of the school. Adam is wearing a white cotton T-shirt and Mary is wearing a black cotton T-shirt. Who is going to feel cooler in direct sunlight and why?

• Adam, because white reflects more radiant energy than black.

• Mary, because black reflects more radiant energy than white.

• Adam because white absorbs more radiant energy than black.

• Neither, because the color of their shirt does not change have any impact on the temperature they feel in the sunlight.

In an experiment, you were instructed to heat a sample of soil and a sample of water with heat lamps and then measure the temperature of each sample every minute, for 20 minutes. The results from the first 8 minutes of the test are shown in the table below. Which of the following quantitative observations can be made based on the data collected?

• The temperature of the soil and the water continued to increase at the same rate.

• The temperature of the soil did not increase at all in the experiment.

• The temperature of the water increased at a faster average rate than the soil’s temperature.

• The temperature of the soil increased at a faster average rate than the water’s temperature.

A pot is made of aluminum, but the pots handles are plastic. Why are these materials used in this way?

• Aluminum is a conductor of heat, which allows the pot’s temperature to increase rapidly, while plastic is a heat insulator, preventing rapid heat transfer and keeping the handles cool.

• Plastic is a heat conductor, which allows heat to move quickly out of the handles, keeping the handles cool, while aluminum is a heat insulator that holds the heat within the pot.

• Both aluminum and plastic are heat conductors that allow heat to be transferred throughout the pot.

• Both aluminum and plastic are heat insulators that keep the heat contained within the pot.

If one part of a solid object is at a higher temperature and another part of the same object is at a lower temperature, the heat is transferred within the object through which process?

• convection

• insulation

• radiation

• conduction

In a mini fridge, the icebox is suspended from the top. What is the purpose of this?

• Warm air from the rest of the refrigerator will have more kinetic energy and rise to the icebox, making the fridge colder.

• Cold air from the rest of the refrigerator has less kinetic energy and will rise to the icebox, making the icebox colder.

• Cold air from the icebox will have less kinetic energy and sink to the rest of the refrigerator, making the fridge colder.

• Warm air from the icebox will have more kinetic energy and sink to the rest of the refrigerator, making the icebox colder.

Julia was wading through a shallow, slow-moving river searching for stones. She observed a unique rock and went to grab it. When she initially reached down for it, it wasn’t in the spot it appeared through the water. Why was the position of the rock not as it appeared to be?

• 
  The waves of light are bending when they enter a new medium due to refraction.

• The waves of light are experiencing constructive interference when they enter the water.

• The rock appears to be in the water, but it is not really because the light waves are being reflected.

• The water is translucent and making the light waves scatter, so the rock is not clearly visible.

You pick up a can of soda off the countertop. The countertop underneath the can feels colder than the rest of the counter. Which explanation best describes the difference in temperature?

• The cold has been transferred from the soda to the counter.

• There is no heat energy left in the counter beneath the can.

• Some heat has been transferred from the counter to the soda.

• The heat beneath the can moves away into other parts of the countertop.
