18 Questions
When water vapor condenses, the surrounding air becomes:
warmer due to the release of latent heat
The amount of energy released when 1 gram of water vapor at 100°C condenses to liquid water at 100°C is:
540 calories
The specific heat capacity of water is higher than that of most other substances because:
water molecules form hydrogen bonds
The role of oceans in temperature regulation is primarily due to:
the high specific heat capacity of water
The rate of evaporation from the ocean's surface is primarily influenced by:
all of the above
The amount of energy absorbed or released when 1 gram of water at 0°C freezes to ice at 0°C is:
80 calories
If 1 kg of water at 20°C is mixed with 1 kg of water at 40°C, what will be the final temperature of the mixture?
30°C
Why does the evaporation of water from a dog's tongue help to cool its body?
The evaporation process absorbs heat energy from the dog's body, causing cooling.
Which of the following statements about the specific heat capacity of water is correct?
Water has a high specific heat capacity, which means it can absorb a large amount of heat energy with a small temperature change.
What role do oceans play in regulating the Earth's temperature?
Oceans absorb and release heat energy, helping to moderate temperature changes on land.
How does heat transfer occur in the ocean?
All of the above mechanisms (conduction, convection, and radiation) play significant roles.
What is the primary reason for the formation of dew on the surface of a cold soft drink bottle?
The cold temperature of the bottle causes water vapor in the air to condense.
Which of the following factors does NOT affect the rate of evaporation?
Pressure exerted by the liquid itself
Why does the ocean water help moderate the surrounding temperature near the equator?
The high specific heat capacity of water allows it to absorb large amounts of heat without a significant rise in temperature.
What is the primary mechanism by which the oceans help stabilize temperatures on Earth during winter and summer seasons?
The oceans transport heat from the equator to the polar regions through ocean currents.
If the atmospheric vapor pressure increases, what effect will it have on the rate of evaporation?
The rate of evaporation will decrease.
Which of the following statements about the specific heat capacity of water is correct?
Water has a high specific heat capacity, which means it requires a large amount of energy to change its temperature.
What role do ocean currents play in stabilizing atmospheric temperatures during winter and summer seasons?
Ocean currents transport heat from the equator to the polar regions, moderating temperatures in those areas.
Learn about how evaporation depends on surface area and the surrounding environment through a simple experiment with spirits in different rooms. Understand the impact of vapor already present in the surroundings on the rate of evaporation.
