How much heat energy is needed to heat 300g of water from 10 degrees Celsius to 50 degrees Celsius

There is 50.2 kJ heat need to heat 300 gram of water from 10° to 50°C

Explanation:

Step 1: Data given

mass of water = 300 grams

initial temperature = 10°C

final temperature = 50°C

Temperature rise = 50 °C - 10 °C = 40 °C

Specific heat capacity of water = 4.184 J/g °C

Step 2: Calculate the heat

Q = m*c*ΔT

Q = 300 grams * 4.184 J/g °C * (50°C - 10 °C)

Q = 50208 Joule = 50.2 kJ

There is 50.2 kJ heat need to heat 300 gram of water from 10° to 50°C
