What makes heat capacity higher?
The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the swimming pool of water has a larger heat capacity than the bucket of water.
What molecule has the highest heat capacity?
Water
Water has the highest heat capacity of all liquids.
Which has highest specific heat capacity water or hydrogen?
Water has a high specific heat capacity because it has hydrogen bonds between molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move randomly. Water has the highest specific heat capacity compared to other substances.
What does a higher heat capacity mean?
The higher the specific heat capacity, the smaller the temperature change for the same amount of heat applied to the same mass of substance.
How does hydrogen bonding affect specific heat?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. In fact, the specific heat capacity of water is about five times more than that of sand. This explains why the land cools faster than the sea.
Which of the following has the highest specific heat capacity?
water
So by comparing the values of the specific heat we can see that the maximum specific heat is of water. The correct option for this problem is option A. Additional information: The heat generated on any substance is equal to the product of mass, specific heat of the substance and change in temperature.
What is the specific heat capacity of hydrogen?
Specific heat capacity
| J/(mol·K) | J/(g·K) | |
|---|---|---|
| 1 H hydrogen (H2, gas) | ||
| use | 20.786 | 1.030 |

| WEL | 20.786 |
Does higher specific heat mean higher temperature?
Explanation: Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Why is high heat capacity important?
Why heat capacity is important The high specific heat of water has a great deal to do with regulating extremes in the environment. For instance, the fish in this pond are happy because the specific heat of the water in the pond means the temperature of the water will stay relatively the same from day to night.
Which of these has the highest specific heat capacity?
Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
What is high heat of fusion?
3 Heat of Fusion. The heat of fusion of water is unusually high. The heat of fusion is the quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change (Weast, 1964, p. The high heat of fusion of water is used in frost control.
Why is it important that water has a high latent heat of vaporization?
Thus a liquid can flow, unlike a solid. The energy required to completely separate the molecules, moving from liquid to gas, is much greater that if you were just to reduce their separation, solid to liquid. Hence the reason why the latent heat of vaporization is greater that the latent heat of fusion.
