I'd Say B :) Your Welcome LOL!!!!!
Answer:
121550 J
Explanation:
Parameters given:
Mass, m = 0.34kg
Specific heat capacity, c = 14300 J/kgK
Change in temperature, ΔT = 25K
Heat gained/lost by an object is given as:
Q = mcΔT
Since ΔT is positive in this case and also because we're told that heat was transferred to the hydrogen sample, the hydrogen sample gained heat. Therefore, Q:
Q = 0.34 * 14300 * 25
Q = 121550J or 121.55 kJ
Heat is added to the system.
The relation between thermal energy and temperature change in mass is given by the following expression
q = m•C•ΔT
where q is the quantity of heat transferred
m is the mass
C is the heat capacity of the material
ΔT is the temperature change
