How do you solve specific heat capacity problems?

How to calculate specific heat capacity?

1. Find the initial and final temperature as well as the mass of the sample and energy supplied.
2. Subtract the final and initial temperature to get the change in temperature (ΔT).
3. Multiply the change in temperature with the mass of the sample.

How do you find specific heat capacity?

Method

1. Place an electrical immersion heater into the central hole at the top of the weighed metal block.
2. Connect the heat in series with an ammeter and in parallel with a voltmeter.
3. Place the thermometer into the smaller hole.
4. Insulate the block by wrapping it with cotton wool.
5. Record the temperature of the block.

Is specific heat capacity in physics?

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of one kg of water by 1 °C.

How much energy will it take to raise 3 kg of water by 5 c water has a specific heat capacity of 4200 J kg c?

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C….Heat capacity.

Material Specific heat capacity (J/kg/°C)
Copper 385

How many joules are required to raise the temperature of 450 ml of water from 30 c to 100 c?

Answer: 25,200 J (or 25.2 kJ). Explanation: Hope this helps!

How do you calculate the specific heat of water?

The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.

How do you find the specific heat capacity of a liquid?

To determine the specific heat capacity of another liquid, you could pour a measured mass of the hot liquid into the calorimeter (whose heat capacity is now known), and measure the fall in temperature of the liquid and the rise in temperature of the calorimeter, and hence deduce the specific heat capacity of the liquid …

What factors affect specific heat capacity?

This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material . Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance .

Why specific heat is different for different materials?

Each substance will have a different mass, so when the amount of heat and the change in temperature are held constant, the only variable is the mass. Therefore, because mass is the only variable, so because substances have different masses, they will have different specific heats.

What affects specific heat capacity?

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 work out specific heat capacity?

Thermal energy passing out of the beaker into the air – Use an insulator with a lower thermal conductivity.

• Not all thermal energy passing into the oil – Ensure that immersion heater is fully submerged.
• Incorrect reading of thermometer – Use an electronic temperature probe.
• Thermal energy not being spread through the oil – Stir the oil.
• 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 are some examples of specific heat capacity?

Specific Heat Capacity Examples. Water has a specific heat capacity of 4.18 J (or 1 calorie/gram °C). This is a much higher value than that of most other substances, which makes water exceptionally good at regulating temperature. In contrast, copper has a specific heat capacity of 0.39 J.
