Question

If the specific heat of water is 4.184 J/g∙°C, how much heat is required to increase the temperature of 1.500g of water from 23 °C to 39 °C? (show your work) Units count

Answer 1

Q = 100.42 J

Step-by-step explanation:

Given data:

Mass of water = 1.500 g

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

Heat required = ?

Initial temperature = 23°C

Final temperature = 39°C

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 39°C - 23°C

ΔT = 16°C

Q = 1.500 g× 4.184 J/g.°C ×16°C

Q = 100.42 J
