A copper block of mass 500gm and specific heat 0.1 cal/gm c is heated from 30 c to 290 c the thermal capacity of the block.
Answer) 50 cal/c
50cal/c
Gud
To calculate the thermal capacity of the copper block, we need to multiply the mass of the block (m), the specific heat of copper (c), and the change in temperature (ΔT).
Given:
Mass of copper block (m) = 500 gm
Specific heat of copper (c) = 0.1 cal/gm °C
Change in temperature (ΔT) = 290 °C - 30 °C = 260 °C
Now, to calculate the thermal capacity:
Thermal capacity (C) = mass (m) x specific heat (c) x change in temperature (ΔT)
= 500 gm x 0.1 cal/gm °C x 260 °C
= 5000 cal/°C x 260 °C
= 1,300,000 cal/°C
≈ 50 cal/°C
Therefore, the thermal capacity of the copper block is approximately 50 cal/°C.
When the mass of substance is multiplied with the specific heat the product is equal to heat (thermal) capacity, which is donated as C.
C= 500*.1 calories per degree C
