Thermal Energy and Heat: Lesson 3 - Science Fusion

Inside a room, the air is often warmer near the ceiling than near the floor. Which of the following accounts for this difference in temperature?

• radiation

• insulation

• convection

• conduction

Addison warms a pure, solid substance. He records the changes in temperature over time in the left-hand column of the following data table. In the right-hand column, he records the state of the substance.

Which of the following could represent the missing values in Addison’s data table?

• X = 50; Y = 100; Z = 50

• X = 50; Y = 100; Z = 150

• X = –50; Y = –100; Z = –50

• X = –50; Y = –100; Z = –150

How is temperature related to heat?

• Temperature is a measure of the heat of an object.

• Heat causes a change in the temperature of an object.

• Raising the temperature causes the heat of an object to increase.

• Temperature and heat are two different ways to measure the same thing.

Sarah heated two cubes of aluminum to 50°C. Cube A has a volume of four cubic centimeters. Cube B has a volume of two cubic centimeters. If the cubes do not touch each other, which of these statements is true?

• Cube A has a higher temperature than cube B.

• Cube B has a higher temperature than cube A.

• Cube A has more thermal energy than cube B.

• Cube B has more thermal energy than cube A.

Which two units of measurement are commonly used to measure heat?

• calorie and joule

• joule and degree Celsius

• calorie and degree Celsius

• degree Celsius and degree Fahrenheit
