Question

the specific heat capacity of a substance is 500J/kg/oC. Find the heat required to rise the temperature of 10 quintial of the substance by 3 degree celcius

Answer 1

• Heat capacity=c=5000J/kg°C
• Mass=10quintal=1000kg=m
• Temeperature=T=3°C
• Heat=Q

`\boxed{\sf Q=mc\Delta T}`

`\\ \sf\longmapsto Q=1000(5000)(3)`

`\\ \sf\longmapsto Q=15000000J`

`\\ \sf\longmapsto Q=1.5* 10^7J`
