all the following are true about water except that it:

a has a very high specific heat capacity compared to ther substances.
b. takes a long time to heat up.
c. takes a short time to cool off.
d. makes the earths climates milder.

c. takes a short time to cool off.

To determine which statement is NOT true about water, let's examine each option and its relationship to water:

a) Water has a very high specific heat capacity compared to other substances. This statement is true. Water's high specific heat capacity means that it requires a large amount of energy to raise its temperature compared to other substances.

b) Water takes a long time to heat up. This statement is true. Water has a high heat capacity, so it takes longer to heat up compared to substances with lower specific heat capacities.

c) Water takes a short time to cool off. This statement is false. Water actually has the ability to retain heat for a relatively longer time compared to many other substances. It can cool off slowly due to its high heat capacity.

d) Water makes the Earth's climates milder. This statement is true. Water has the ability to moderate temperature changes in its surroundings. It helps stabilize climate regions by absorbing and releasing heat slowly which, in turn, affects temperature and weather patterns.

From the options given, option (c) "takes a short time to cool off" is the statement that is NOT true about water.
