Question

What is the amount of heat absorbed when the temperature of 75 grams of water increases from 20 to 75

Answer 1

55°C

Step-by-step explanation:

original is 20

after gaining heat is 75

75 - 20 = 55

Answer 2

17242,5J

Step-by-step explanation:

Given parameters:

Mass of water = 75g

Initial temperature = 20°C

Final temperature = 75°C

Unknown:

Amount of heat absorbed = ?

Solution

To find the amount of heat absorbed by water;

H = mcΔt

m is the mass

c is the specific heat capacity of water = 4.18J/g°C

Insert the parameters and solve;

H = 75 x 4.18 x (75 - 20)

H = 17242,5J
