Question

1. the amount of heat needed to increase the temperature of a certain mass of a substance by 1°c is its
2. true or false? compared with other substances, water requires a lot of heat to increase its temperature.
3. circle the letter of each sentence that is true about waters specific heat.

a. it is due to the many attractions among water molecules.
b. it makes large bodies of water heat up more quickly than nearby land.
c. it makes large bodies of water cool off more slowly than nearby land.
d. it leads to warmer air over land than over water on summer days.

1. how does the high specific heat of water affect your body?

Explanation:

1. Specific heat is the amount of heat required to raise the temperature of a unit - mass of a substance by 1°C, so the statement is True.
2. Water has a high specific heat. Compared to other substances, it requires a large amount of heat to increase its temperature, so the statement is True.

19.

• a. Hydrogen - bonding between water molecules leads to many attractions among water molecules, which is related to water's high specific heat, so this is true.
• b. Land has a lower specific heat than water, so large bodies of water heat up more slowly than nearby land, this is false.
• c. Large bodies of water cool off more slowly than nearby land due to high specific heat, this is true.
• d. On summer days, the high - specific heat of water means it leads to cooler air over water than over land, this is false.

1. Water's high specific heat helps regulate body temperature. It can absorb and release a large amount of heat without a large change in its own temperature. This property helps maintain a stable internal body temperature. For example, when the body generates heat, water in the body can absorb the excess heat. When the body is cold, water can release heat to warm the body.

Answer:

1. True
2. True
3. a. True, b. False, c. True, d. False
4. Water's high specific heat helps regulate body temperature by absorbing and releasing heat to maintain a stable internal temperature.
