Question

Heat absorbed or released by a substance can be calculated with the equation _____________.

q = m × Cs × ∆T
q = m × Cs ÷ ∆T
q = m + Cs + ∆T
q = m + Cs

Answer 1

q = m × Cs × ∆T is the correct equation to calculate the amount of heat absorbed or released by a substance, where:

• q is the amount of heat (in joules or calories)

•m is the mass of the substance (in grams or kilograms)

•Cs is the specific heat capacity of the substance (in joules per gram per degree Celsius or per Kelvin)

•∆T is the change in temperature of the substance (in degrees Celsius or Kelvin)
