In the isochoric process, 4 * 10 ^ 10 J of heat is reported to the gas to calculate the change in internal energy and the work of expanding the gas.

isochoric process
the gas is reported 4 * 10 to the power of 10 J of heat
find the change in the internal energy for the expansion of the gas
decision
remember the isochoric process
with this process, the volume remains unchanged
work with isochoric process is 0
then we get the expression Q = A + dU = 0+ dU, where Q = 4 * 10 ^ 10 J
from here we get that
dU = Q = 4 * 10 ^ 10 J
answer dU = Q = 4 * 10 ^ 10 J
