What are two things that affect how much heating is required to raise the temperature of water?
Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.
What is high for water so it requires a lot of energy to increase its temperature?
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. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Why does water need a lot of heat to raise the temperature?
It takes a lot of heat to increase the temperature of liquid water because some of the heat must be used to break hydrogen bonds between the molecules. Because of its high heat capacity, water can minimize changes in temperature.
What refers to the amount of heat needed to raise the temperature of a substance by 1c?
heat capacity
heat capacity: The amount of heat required to raise the temperature of an object by 1°C.
How do you get the amount of heat needed to change the temperature of a substance?
When heat transfer is involved, use this formula: change in temperature = Q / cm to calculate the change in temperature from a specific amount of heat added. Q represents the heat added, c is the specific heat capacity of the substance you’re heating, and m is the mass of the substance you’re heating.
Does the temperature of the water affect how much energy it takes to raise the temperature higher?
An equal mass of water in the same sun will not become nearly as hot. We would say that water has a high heat capacity (the amount of heat required to raise the temperature of an object by 1°C.)… Heat Capacity and Specific Heat….
| Substance | Specific Heat (J/g°C) |
|---|---|
| Water (s) | 2.06 |
| Water (g) | 1.87 |
| Ammonia (g) | 2.09 |
In which will more heat be required to increase the temperature by 1 C?
water
We would say that water has a high heat capacity (the amount of heat required to raise the temperature of an object by 1°C.) Water is very resistant to changes in temperature, while metals in general are not.
