Web2 6.3 Heat Measurements • Heat transfer in or out of an object can be estimated by measuring the temperature change in the object • Heat capacity – the heat required to increase the temperature of an object by 1 K (or ºC) Heat capacity= q/∆T – units J/K or J/ºC • The heat capacity is an extensive property WebFeb 5, 2024 · The equation for the change in internal energy is deltaU = q+w but you have to determine whether work is being done on the system or by the system. If work is being done by the system (losing energy), w will be negative, so in that case, it would be q-w. Top. 305589333 Posts: 54
WebOct 12, 2024 · The first law of thermodynamics is given as Δ E = q + w, where Δ E is the change in internal energy of a system, q is the net heat transfer (the sum of all heat transfer into and out of the system), and w is the net work done (the sum of all work done on or by the system).
