Question

It requires 2.500 joules to raise a certain amount of water
(C = 4.186 Jlg°C) from 20.0°C to 60.0°C.
OOOO
What is the mass of the water that is being heated?
O 159
O 409
O 639
O 809

Answer 1

Answer:

Explanation:

The heat absorbed from the heating of water can be calculated by the product of the mass of the sample, specific heat and the difference in temperature. From the given data, we can simply calculate the mass of the sample as follows:

H = mC(T2-T1)

2500 = m(4.186)(60-20)

m = 14.93 g

Answer 2

O 809.

The heat absorbed from the heating of water can be calculated by the product of the mass of the sample, specific heat, and the difference in temperature. From the given data, we can simply calculate the mass of the sample as follows:

H = mC(T2-T1)

2500 = m(4.186)(60-20)

m = 14.93 g.

What is an example of energy conversion?

Energy can be converted from one form to another. Examples: Gasoline (chemical) is put into our cars, and with the help of electrical energy from a battery, provides mechanical (kinetic) energy. Purchased electricity is fed into our TVs and is converted to light and sound.
