Question

Calculate required heat energy (Q) to heat 10gm of water from 30°C to 40°C (water specific heat =1)

Answer 1

Answer:

Mass of water = 10gInitial temperature = 30°CFinal temperature = 40°CWe have to find heat required to raise temperature of water.. Specific heat of substance is defined as the heat required to increase temperature of 1g substance by 1°C. Specific heat of water = 1 cal/g °CFormula : Q = mcΔT☃ Let's calculate :D.
