What are properties in thermodynamics?

Properties are point functions that depend on the state only.

Define heat in the context of thermodynamics.

Heat is defined as the form of energy transferred between systems by virtue of a temperature difference.

What is work in the context of thermodynamics?

Work is energy transfer that occurs when something moves against an opposing force.

How does energy transfer occur in a closed system?

Energy can cross the boundary of a closed system in two forms: heat and work. Signup and view all the answers

What are heat and work considered in relation to a system?

Both heat and work are recognized at the boundaries of a system as they cross the boundaries. Signup and view all the answers

Why are heat and work not considered properties in thermodynamics?

Heat and work are not properties because their amounts depend on more than just the state of the system. Signup and view all the answers
