Why is water used as a coolant in car engines?
Water is used as a coolant in car engines because it is cheap and easily accessible.
Water is used as a coolant in car engines because of its high specific heat capacity, high boiling point, and availability.
Water is used as a coolant in car engines because it helps to reduce friction in the engine.
Water is used as a coolant in car engines because it helps to improve fuel efficiency.
How does specific heat affect the temperature change of a substance?
Specific heat determines the amount of heat energy required to change the temperature of a substance.
Specific heat determines the density of a substance.
Specific heat determines the color change of a substance.
Specific heat has no effect on the temperature change of a substance.
What are some applications of specific heat in everyday life?
Determining the melting point of metals, measuring the temperature of the human body, and calculating the energy consumption of electronic devices.
Cooking, heating and cooling systems, and determining the energy content of food.
Why is it important to consider specific heat when designing heating and cooling systems?
Specific heat helps determine the amount of energy needed for heating and cooling systems.
Specific heat has no impact on heating and cooling systems.
Specific heat is only relevant for industrial heating and cooling systems.
Specific heat only affects the temperature of the system, not the energy needed.
Liquid water can store more heat energy than an equal amount of any other naturally occurring substance because liquid water
covers 71% of Earth's surface
has its greatest density at 4ºC
has the higher specific heat
can be changed into a solid or a gas
How do the rates of warming and cooling of land surfaces compare to the rates of warming and cooling of ocean surfaces?
Land surfaces warm faster and cool more slowly.
Land surfaces warm more slowly and cool faster.
Land surfaces warm faster and cool faster.
Land surfaces warm more slowly and cool more slowly.
The same amount of heat energy is added to equal masses of lead, iron, basalt, and water at room temperature. Assuming no phase change takes place, which substance will have the smallest change in temperature?
lead
iron
basalt
water
Land surfaces of Earth heat more rapidly than water surfaces because
more energy from the Sun falls on land than on water
land has a lower specific heat than water
sunlight penetrates to greater depths in land than in water
less of Earth's surface is covered by land than by water
