Find the heat needed to raise the temperature of a silver container of mass 100g by 10°C. (c=0.056 cal/g °C)​

Answer»

Given :

  • Mass of silver = 100G
  • c = 0.056 cal/(g °C)
  • Temperature change = ∆T = 10°C

To find :

HEAT required

Formula used :

Q = m × c × ∆T

Here,

  • Q = Heat required
  • m = mass
  • c = Specific heat capacity
  • ∆T = Change in temperature

Solution :

Q = m c ∆T

➝Q = 100g × 0.056 cal/(g °C) × 10°C

➝ Q = 100 × 10 × 0.056 cal

➝ Q = 1000 × 0.056 cal

➝ Q = 56 cal

ANSWER : 56 cal
