Specific heat capacity of water is 4200 J/kg⁰C. How much energy is needed to raise thetemperature of 3kg of water by 4⁰C?
Question
Solution 1
To calculate the energy needed to raise the temperature of a certain amount of water, we can use the formula:
Q = mcΔT
where:
- Q is the heat energy (in Joules)
- m is the mass of the substance (in kg)
- c is the specific heat capacity (in J/kg°C)
- ΔT is the change in temperature (in °C)
