Question 1
Less water boils faster due to quicker temperature rise.
Question 2
What is thermal energy in solids?
Question 3
Heat energy is the amount of thermal energy that is _____.
Question 4
CASE STUDY: A chef is heating two pots of soup, one with more soup than the other. The pot with less soup reaches boiling point faster.
Why does the smaller pot boil faster?
Question 5
CASE STUDY: A physicist compares the heating of two metal rods, one shorter than the other. The shorter rod heats up more quickly.
Select three factors for quicker heating of shorter rod.
Question 6
Heat energy is the same as thermal energy.
Question 7
How is heat transferred in a vacuum?
Question 8
The sum of kinetic energy of all particles is called _____.
Question 9
CASE STUDY: An engineer is designing a heating system for two different-sized water tanks. The smaller tank heats up more quickly.
What causes the smaller tank to heat faster?
Question 10
Convection involves movement of matter to transfer thermal energy.
Question 11
What increases when heat is added to water?
Question 12
Temperature is a measure of the _____ kinetic energy of particles.
Question 13
Radiation transfers thermal energy without matter.
Question 14
Why does less water boil faster?
Question 15
In solids, thermal energy is mainly due to _____ kinetic energy.
Question 16
Temperature and thermal energy are the same concept.
Question 17
