Answer

Liters per mole

Question 3

What is the formula for calculating heat?

Accepted Answer

Q = mcΔT

Answer

Q = mc/tΔ

Answer

Q = tcΔ/m

Answer

Q = mtΔc

Question 4

What effect does a higher specific heat have on a substance?

Accepted Answer

It means the substance can store more heat energy without its temperature changing as much

Answer

It means the substance is easier to heat up

Answer

It has no effect on the substance

Answer

It means the substance is harder to heat up

Question 5

What does 'Q' represent in the specific heat equation?

Accepted Answer

Heat energy absorbed or released

Answer

Mass of the substance

Answer

Change in temperature

Answer

Specific heat capacity

Question 6

What is the specific heat of water?

Accepted Answer

4.184 J/(g·°C)

Answer

8.345 J/(g·°C)

Answer

3.141 J/(g·°C)

Answer

1.987 J/(g·°C)

Question 7

What is the equation for calculating the change in temperature?

Accepted Answer

ΔT = Q/mc

Answer

ΔT = Q/mc²

Answer

ΔT = mc/Q

Answer

ΔT = Q/mc₀

Question 8

What is the equation for calculating the mass of a substance given its specific heat, change in temperature, and heat energy absorbed or released?

Accepted Answer

m = Q/(cΔT)

Answer

m = QcΔT

Answer

m = Q/(ΔT/c)

Answer

m = cΔT/Q
