The specific heat of substance X is 200 J/g*C, how much heat is required to change the temperature of 2.0 grams of substance X from 35 degrees Celsius to 55 degrees Celsius?

Respuesta :

c = 200 j/g*C
m = 2g
ΔT = 55 - 35 = 20C

Heat = mcΔT = 2 * 200 * 20 = 8000J = 8kJ

The amount of heat required is 8000 J.

What is heat?

Heat is a form of energy that is due to temperature.

To calculate the amount of heat required, we use the formula below.

Formula:

  • Q = cm(t₂-t₁).......equatiuon 1

Where:

  • Q = Amount of heat required
  • m = Mass of the substance X
  • c = Specific heat capacity of the substance X
  • t₂ = Final Temperature
  • t₁ = Initial temperature.

From the question,

Given:

  • c = 200 J/g°C
  • m = 2.0 g
  • t₂ = 55 °C
  • t₁ = 35 °C

Substitute these values into equation 1

  • Q = 200×2×(55-35)
  • Q = 200×2×20
  • Q = 8000 J

Hence, the amount of heat required is 8000 J.
