What is the relationship between water and heat?
What is the relationship between water and heat?
One of water’s most significant properties is that it takes a lot of energy to heat it. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C.
What is the relation between heat capacity and water equivalent of the body?
“The water equivalent of a body is the mass of water which would take up as much heat as the body when the temperature rise was the same for each.” Water equivalent = mass of body × specific heat. “The thermal capacity of a body is the heat necessary to raise the temperature of the body by one degree.”
How can the specific heat capacity of water be used to determine the amount of energy stored in another substance?
Some substances heat up quickly, while other substances heat up slowly. Water is one of the latter—it has a high specific heat capacity because it requires more energy to raise the temperature. Water has a specific heat capacity of 4182 J/kg°C.
What is the relationship between the heat capacity and specific heat capacity of a substance?
Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.
What happens to the water and its thermal energy is heated?
Continued heating of liquid water causes the molecules to vibrate even faster, steadily raising the temperature. FREEZING When liquid water freezes, it releases thermal energy and turns into the solid state, ice. The result is vaporization— the liquid be-comes a gas.
What is the relationship between the mass of a material and the amount of heat it can transfer?
(b) The amount of heat transferred is also directly proportional to the mass. To cause an equivalent temperature change in a doubled mass, you need to add twice the heat.
