Which of the following statements are true about temperature? Select all that apply. 

• Temperature is determined by cloud cover and wind speed.

• The warmer the temperature the slower the particles move.

• Temperature is a measure of the thermal energy of matter.

• Thermal energy is the kinetic energy of the particles in an object, a unit of liquid, or a parcel of air.

We know that when light hits any matter it can be reflected, absorbed, or refracted. How does the absorption of light affect the temperature of an object?

• When light is absorbed, the temperature holds steady even when the light source is removed.

• We cannot measure the temperature of light energy.

• When light is absorbed, the temperature of the object increases. 

• When light is absorbed, light energy is transformed into thermal energy but it does not affect the temperature of the object.

Lee and Charles are having an argument about why the air feels so warm when the sun is shining. Lee says that energy from the sun heats the air around the Earth.  Charles says that the sun heats the Earth first and that heats the air. Select which person is correct and why?

• They are both right. Earth’s atmosphere (or the air around us) is heated in two ways. Some of Earth’s atmosphere is heated directly by the sun as it transfers thermal energy to the air particles/molecules. The particles move faster and the temperature gets warmer. But, most of the sun’s energy passes through the atmosphere to the surface of the Earth. The surface/ground absorbs thermal energy and then transfers it to the air particles/molecules.

• Charles is correct most of the solar radiation gets absorbed by the Earth and converted to thermal energy.

• Lee is correct. As the sun’s rays move through the atmosphere, most of the air molecules are directly heated by light energy.

• Neither is correct. The water vapor in the atmosphere releases thermal energy as it condenses to form clouds. The thermal energy heats the air molecules.

How is thermal energy transferred through the metal rod which causes the balls of shortening to drop one at a time?

• The increased energy from the candle makes the electrons travel through the metal and heats it.

• As the hot plate burned, thermal energy was transferred to the metal rod causing the particles in the metal in move faster. When the faster moving particles collided with the slower moving particles some of the energy was transferred to the slower moving particles causing them to move faster and increase the thermal energy along the rod.

• The thermal energy from the candle is absorbed through radiation. The metal is able to radiate the heat energy out the end of the rod.

• The metal absorbs heat and expands which loosens the balls of shortening causing them to fall.

Which of the following statements are true about conduction? Select all that apply.

• Conduction does not occur within one object. The energy transfer is between two or more objects or types of matter.

• In conduction, particles collide and transfer energy from one particle to another.

• For conduction to occur, two objects (matter) must be in contact with each other.

• Most of the air molecules in our atmosphere are heated by conduction.

We live in the lowest layer of the atmosphere called the troposphere, this is where weather occurs. A student claims that the kinetic energy of water particles decreases as they rise in an air mass. What is evidence that would support the student’s claim?

• The warmest temperatures are at the lowest height in the layer of the atmosphere closest to Earth.

• There are more water particles at the bottom of the layer of the atmosphere closest to Earth.

• The temperature of the atmosphere decreases proportionally with height.

• Clouds form in the lowest height of the layer of the atmosphere closest to Earth.
