The specific heat capacity of liquid water is 4.18 j/g-k.

how many joules of heat are needed to raise the temperature of 5.00 g of water from 25.1°c to 65.3°c?

The amount of heat required to raise the temperature of the water has been 6.549 kJ.

The specific heat can be defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius.

Q = mcT

Q = heat required

m = mass = 5 g

c = speific heat capacity = 4.18 J/g K

T = change in temperature = 65.3 - 25.1

T = 40.2

T = 313.35 K

Q = 5 4.18 313.35 K

Q = 6,549.015 J

Q = 6.549 kJ.

The amount of heat required to raise the temperature of the water has been 6.549 kJ.

840.18

Explanation:

Use the equation: Q = mcΔT

m = mass (5 g)

c = specific heat (4.18)

ΔT = change in temperature (65.3-25.1 = 40.2)

= 840.12
