This means to heat one gram of water by one degree Celsius, it would require 4.18 joules of energy.
A series of free GCSE/IGCSE Physics Notes and Lessons.
These three specific heat example problems will show how to find the specific heat of a material or other information involving the specific heat.
The equation most commonly associated with specific heat is Q = mcΔTwhere Q = Heat energy m = mass c = specific heat ΔT = change in temperature = (T)A good way to remember this formula is Q = “em cat”Basically, this equation is used to determine the amount of heat added to a material to raise the temperature some amount (or the amount lost as the material cools).
Calculate the energy required to increase the temperature of 2kg of water from 20°C to 100°C.
The specific heat capacity of water is 4200 J/kg °C. An iron has an aluminium plate with a mass of 1.5kg.
Calculate the mass of the water in the hot water bottle.
The specific heat capacity of water is 4200 J/kg°C.
Usually, the lowercase letter "c" is used to denote specific heat.
The equation is written: where Q is the heat that is added, c is specific heat, m is mass and ΔT is the change in temperature.
