what is the temperature change in Celsius when 29.5 L of what absorbs 2.3 kWh of heat?

To find the temperature change in Celsius, we can use the equation:

Q = mcΔT,

where Q is the heat absorbed, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.

However, the given information is not sufficient to directly calculate the temperature change since we do not know the specific heat capacity or the initial and final temperatures.

If you have additional information, such as the specific heat capacity of the substance or the initial and final temperatures, please provide it so that we can assist you further.
