Question

20 cal × of energy required to 10 g of a substance, whose specific heat is 0.5 cal / g°C. The raisein temperature is​

Answer 1

Given:

• Heat required by the substance (Q) = 20 cal
• Mass of the substance (m) = 10 g
• Specific heat of the substance (c) = 0.5 cal/g°C

To find:

The rise in temperature of the substance (θ).

Solution:

• The amount of heat required by a substance of mass 'm' and specific heat capacity 'c' to raise the temperature of the substance by θ°C is equal to mcθ.
• Therefore, Q = mcθ ⇒ θ = Q/(mc) = 20/(10*0.5) = 4°C

Answer:

The rise in temperature of the substance (θ) = 4°C.
