Why does water heat up more slowly than land?

Answer 1

The molecules that compose or make up a solid, such as land, need more energy or in this case heat, to move them. The molecules are compact where as in liquid they have more mobility. When a substance heats, its molecules move faster. Since liquid's molecules have more mobility, liquid heats more quickly.

Answer 2

2 reasons:

1) water molecules are generally closer together than the molecules that make up the land. Therefore, the heat is trapped inside those close molecules, just like heat would be trapped inside a tight jacket rather than a loose sweater.

2) water molecules are polar, therefore heat is kept for longer in those polar molecules. Land doesn't generally have that same "heat carrying capacity" because it isn't polar.

Answer 3

This is due to a property of material things called their "thermal capacity" or "specific heat capacity". Basically it is a measure of how much energy it will take to raise the temperature of a unit mass of something by a unit of temperature and conversely how much energy is given out when that mass drops in temperature.

The specific heat capacity of water is 4181 J/ kg °C

The specific heat of Dolomite Rock is 92 J/ kg °C

Thus as you can see it take a lot more energy to heat up water than rock (land). As the energy comes from the Sun at a constant rate it will take more hours of sunshine it will take 45 times as long to heat up water as compared to rock.

Thus on a sunny day the ocean remains a cool place to swim while in a sunny desert you could cook an egg on the ground at midday.

Also the water (oceans) store a lot of energy and move this round the planet.

Answer 4

this happens because water(in the oceans ) has a higher specific heat capacity than land causing it to heat up slowly and even lose heat slowly

Answer 6

Because it has more thermal mass.
