# Is specific heat in Joules or kilojoules?

## Is specific heat in Joules or kilojoules?

Specific heat is typically measured in Joules and kilojoules per one gram of mass, with Celsius as a measure of temperature. Kilograms and Fahrenheit may be used, but it’s rarer.

## How do you convert kilojoules to Joules?

To convert a kilojoule measurement to a joule measurement, multiply the energy by the conversion ratio. The energy in joules is equal to the kilojoules multiplied by 1,000.

Is specific heat measured in Joules?

Therefore, specific heat is measured in Joules per g times degree Celsius.

### What is Q MCP ∆ T?

Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.

### What is the formula for kJ?

1 Joule (J) is equal to 0.001 kilojoule (kJ). To convert joules to kilojoules, multiply the joule value by 0.001 or divide by 1000. For example, to convert 100 J to kJ, divide 100 by 1000, that makes 0.1 kJ is 100 J.

Is kJ and J the same?

1 Kilojoule (kJ) is equal to 1000 joules (J). To convert kilojoules to joules, multiply the kilojoule value by 1000.

## Why is CP is greater than CV?

cp is greater than CV because when gas is heated at constant volume,whole of the heat supplied is used to increase the temperature only. But when gas is heated at constant pressure,the heat supplied is used to increase both temperature and volume of gas.

## How is Q system calculated?

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.

What is CP equal to?

Cp and Cv are specific heat at constant pressure and volume and, are important thermodynamic properties, given to the solution as input. Say for air, at atmospheric pressure, Cp=1.005 kJ/kgK. For some situations we just let h and u to remain as it is.

### How many Joules is 3000 Watts?

Convert 3000 Watt Hour to Joules

3000 Watt Hour (Wh) 10,799,991 Joules (j)
1 Wh = 3,600 j 1 j = 0.000278 Wh

### How many Joules is 1000 Watts?

A kilowatt is equal to 1000 watts, so 1 kWh represents the amount of energy transfer that occurs over one hour from a power output of 1000 watts (i.e., joules per second). Thus 1 kWh is equal to 3,600,000 joules of energy transfer (work).

What is wattage formula?

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current.

## What is meant by 1 joule work?

Joule is the SI unit of work. 1 Joule is amount of work done when a force of 1 Newton displaces a body through a distance of 1m in the direction of the force applied.
