## How do you find the specific heat capacity of water experiment?

1. Given that the specific heat capacity of the calorimeter ccal is known, the specific heat capacity of water cw can be calculated from the following equation: Electrical energy supplied = energy gained by water + energy gained by calorimeter Q = mwcw + mcalccal .

How does specific heat capacity relate to water?

Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.

What is the specific heat capacity of the water?

4182 J/kg°C.
The exact value of the specific heat capacity of water is 4182 J/kg°C. Now, water is quite commonly occurring and an important substance in our life. Therefore, there is a special way to identify the total amount of heat energy needed to raise one gram of water by a calorie (one degree Celsius).

### What is the specific heat capacity of water in JGC?

4.18 J/g°C
The specific heat of water is 4.18 J/g°C.

What does a joulemeter measure?

A joulemeter is an electronic device used to measure the energy transfer by electricity in a circuit.

Does specific heat capacity of water change with temperature?

Specific heat capacity often varies with temperature, and is different for each state of matter. Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1.

## What are the specific heat capacity and molar heat capacity for water?

Molar Heat Capacity Examples Water has a molar specific heat capacity of 75.32 J/mol·K. Copper has a molar specific heat capacity of 24.78 J/mol·K.

Why specific heat capacity of water is high?

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.

What are the specific heat capacity and molar heat capacity for water?]?

Water (liquid): CP = 4185.5 J⋅K−1⋅kg−1 (15 °C, 101.325 kPa) Water (liquid): CVH = 74.539 J⋅K−1⋅mol−1 (25 °C) For liquids and gases, it is important to know the pressure to which given heat capacity data refer.

### How do you use a Joulemeter?

Method 1: Joulemeter

1. connect the Joulemeter to the power pack and the immersion heater.
2. place the immersion heater in the cavity (hole) of the metal block.
3. use a pipette to put a few drops of water in the smaller cavity and place the thermometer in the small cavity.
4. turn on the power pack and start a timer.

How to calculate specific heat capacity?

Q = quantity of heat absorbed by a body

• m = mass of the body
• ∆t = Rise in temperature
• C = Specific heat capacity of a substance depends on the nature of the material of the substance.
• S.I unit of specific heat is J kg-1 K-1.
• How do you find the specific heat capacity?

Example: “I have 100 grams of ice.

• Heat Capacity for 100g Ice = 406J/2C
• Heat Capacity for 100g Ice = 203 J/C
• Heat Capacity for 1g Ice = 2.03 J/C per gram
• If you are confused,think of it this way — it takes 2.03 Joules to raise every single gram of ice one degree.
• ## How to solve specific heat capacity problems?

– The mass of the substance. – The specific heat of the substance. – The temperature change of the substance.

What instrument is used to calculate specific heat capacity?
