How much heat is needed to change the temperature of 3 grams of gold (c = 0.129) from 21°C to 363°C? The answer is expressed to the nearest whole number.

Q = mcΔT

Where Q is heat or energy

M is mass, c is heat capacitance and t is temperature

You have to convert Celsius into kelvin in order to use this formula I believe

Celsius + 273 = Kelvin

21 + 273 = 294K

363 + 273 = 636K

Now ...

Q = (0.003) (0.129) (636-294)

Q = 0.132 J if you are using kilograms, in terms of grams which seems more appropriate the answer would be 132J of energy.

It's 132 or B on edge 2020
