How much energy is required to raise the temperature of 10.5 grams of gaseous neon from 24.2 [tex]^\circ C[/tex] to 37.1 [tex]^\circ C[/tex]?

Answer :

The energy required to raise the temperature of 10.5 grams of gaseous neon from 24.2°C to 37.1°C is approximately 2796.93 joules, calculated using the formula Q = mcΔT.

To calculate the energy required to raise the temperature of a substance, you can use the formula:

Q = mcΔT

Where:

Q is the energy (in joules) required

m is the mass of the substance (in grams)

c is the specific heat capacity of the substance (in J/g°C)

ΔT is the change in temperature (in °C)

Given the following values:

m = 10.5 g

ΔT = 37.1°C - 24.2°C = 12.9°C (change in temperature)

The specific heat capacity of neon at constant pressure (Cp) is approximately 20.8 J/g°C.

Substitute the values into the formula:

Q = (10.5 g) * (20.8 J/g°C) * (12.9°C) = 2796.93 J

The energy required to raise the temperature of 10.5 grams of gaseous neon from 24.2°C to 37.1°C is approximately 2796.93 joules.
