Science study guide Energy and Changes in Matter Lesson 3: Thermal Energy on the Move

b. The movement of _______________ that occurs between a warmer substance, such as hot soup, and a cooler substance, such as surrounding air, causes a change in____________ of both substances.

c. Materials that have small pockets of trapped air make good ____________ because air slows heat flow.

d. When one part of a fluid is ____________ then the rest of the fluid, the warm fluid ___________ and becomes less dense, so it rises. The _________ sinks.

e. With convection, areas of a fluid constantly rise and sink in a loop called a(n) __________.

f. Radiation, unlike ________ and convection, transfers thermal energy through _______________, where no matter exists.

g. Thermal energy is transferred from the Sun to Earth by ______________.

Answer 1

Explanation:

In the last chapter we looked at thermal systems. The thermal energy of an object is the amount of energy it has inside of it, in other words, its internal energy. In a thermal system, thermal energy is transferred from one object to another. Heat is the transfer of thermal energy from a system to its surroundings or from one object to another. This transfer of energy is from the object at a higher temperature to the object at a lower temperature.

Heat is measured in joules (J). This is because heat is a transfer of energy.

Temperature is a measure of the average kinetic energy of the particles in an object or system. We use a thermometer to measure the temperature of an object or substance.
