Question

The specific heat of water is 1.0 calorie/ gram °C. The amount of heat energy needed to raise the temperature of 450 grams of water from 25 °C to 55 °C is: O 15 calories​

Answer 1

Step-by-step explanation:

We can use the equation to find out

E = mc△T

E is the total energy (calories) needed, m for mass, c for specific heat capacity and △T for the temperature change.

Substitute the numbers given

E = 500 x 1 x 10

E =5000

Therefore the answer is 5000CalWe can use the equation to find out

E = mc△T

E is the total energy (calories) needed, m for mass, c for specific heat capacity and △T for the temperature change.

Substitute the numbers given

E = 500 x 1 x 10

E =5000

Therefore the answer is 5000Cal
