Question

How many calories of heat are needed to raise the temperature of 33.0 g of diethyl ether from 14.0 ∘C to 25.0 ∘C ?

Answer 1

The amount of heat (in calories) needed to raise the temperature is 324.885 calories

How to determine the temperature change

We'll begin by obtaining the temperature change. This can be obtained as followed:

• Initial temperature (T₁) = 14 °C
• Final temperature (T₂) = 25 °C
• Change in temperature (ΔT) = ?

ΔT = T₂ - T₁

ΔT = 25 - 14

ΔT = 11 °C

How to determine the heat (in Calories)

The amount of heat needed to raise the temperature can bee obtaimedals follow:

• Mass (M) = 33 g
• Change in temperature (ΔT) = 11 °C
• Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
• Heat (Q) =?

Q = MCΔT

Q = 33 × 0.895 × 11

Q = 324.885 calories

Thus, the amount of heat needed is 324.885 calories
