Question

How much energy is required to raise 10 grams of water by 10 degrees Celsius? (in Joules)

Answer 1

Answer:

420j

Explanation:

Heat capacity =10*4.2*10

=420j

Answer 2

Answer: The amount of heat required by water is 418.6 J

Explanation:

To calculate the heat absorbed by water, we use the equation:

$q=mc\Delta T$

where,

q = heat absorbed

m = mass of water = 10 g

c = heat capacity of water = 4.186 J/g°C

$\Delta T$ = change in temperature = 10°C

Putting values in above equation, we get:

$q=10g\times 4.186J/g^oC\times 10^oC\\\\q=418.6J$

Hence, the amount of heat required by water is 418.6 J
