What unit is specific latent heat measured in?
Specific latent heat is measured in joules per kilogram (J/kg).
Why is a measured amount of water needed to determine the spicific heat of a metal object?
A measured amount of water is used in determining the specific heat of a metal object because water has a well-defined specific heat capacity (1 calorie/gram °C) and is readily available. By measuring the temperature change of a known mass of water when a metal object is immersed in it, and knowing the specific heat of water, we can calculate the specific heat of the metal object.
What is the amount of heat in air?
The amount of heat in air is measured using the specific heat capacity of air, which is about 1 kJ/kg°C. The total heat in air can be calculated by multiplying the specific heat capacity with the mass of air and the change in temperature.
What are the 2 things heat is measured in?
Heat is measured in calories or joules.
Calculate heat of fusion?
The heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is typically measured in joules or calories per gram. The specific heat of fusion for water is 334 J/g.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
What unit is specific latent heat measured in?
Specific latent heat is measured in joules per kilogram (J/kg).
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.

How does the amount of heat transferred to a system can be measured in?
The amount of heat transferred to a system can be measured using a device called a calorimeter, which can measure changes in temperature of the system and surroundings. The heat transfer is quantified in units of energy, typically joules or calories, based on the temperature change and the specific heat capacity of the materials involved.

What is a substance that has a specific heat?
Water is a substance that has a specific heat. Specific heat is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water's high specific heat is what allows it to absorb and release large amounts of heat without drastic temperature changes, making it an important factor in climate regulation and a key component in living organisms.
Why is a measured amount of water needed to determine the specific heat of a metal object?
Because the heat energy absorbed or released by the water is dependent on the mass of the water. q=m x c x delta T The equation tells you that you need a mass, a specific heat and a change in temperature to figure out the specific heat of the metal.
