First law of thermodynamics

Chemistry Level 1

A chemical system is sealed in a strong, rigid container at room temperature, and then is heated vigorously. Determine whether Δ U Δ U and w w are positive, negative, or zero during the heating process.

Δ U < 0 , w = 0 \Delta U < 0, w = 0 Δ U = 0 , w = 0 \Delta U=0, w = 0 Δ U > 0 , w > 0 \Delta U > 0, w > 0 Δ U > 0 , w = 0 \Delta U > 0, w=0
