Back

False

Front

What is the specific heat of water?

Back

All of the above

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity)

Front

What is the definition of specific heat?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.
