Chemistry: If 18.9 J of heat was gained when 2.6 g of O subscript 2 was heated, what was the temperature change that occurred? (The specific heat of O subscript 2 is 0.954 J/g °C)

The temperature change that occurred is 7.62°C

Explanation:

The equation used to calculate heat absorbed follows:

$Q=m\times c\times \Delta T$

where,

Q = heat absorbed = 18.9 J

m = mass of oxygen gas = 2.6 g

c = specific heat of oxygen gas = 0.954 J/g°C

$\Delta T$ = change in temperature = ?

Putting values in above equation, we get:

$18.9J=2.6g\times 0.954 J/g^oC\times \Delta T\\\\\Delta T=\frac{18.9}{2.6\times 0.954}=7.62^oC$

Hence, the temperature change that occurred is 7.62°C
