प्रश्न
The heat capacity of the vessel of mass 100 kg is 8000 J/°K. Find its specific heat capacity.
उत्तर
To calculate the specific heat capacity, we use the formula:
Specific Heat Capacity (c) = `"Heat Capacity"/"Mass"`
Given:
- Heat capacity (C) = 8000 J/°K
- Mass (m) = 100 kg
Substitute the values into the formula:
`c = 8000/100`
c = 80 J/kg·°K.

We would like to make a vessel whose volume does not change with temperature (take a hint from the problem above). We can use brass and iron `(β_(vbrass) = (6 xx 10^(–5))/K and β_(viron) = (3.55 xx 10^(–5))/K)` to create a volume of 100 cc. How do you think you can achieve this.
