Pressure is normal force divided by area. "Normal" refers to the direction of the force, not the type of force. The force can be dissipative. For instance, one can have a normal force that includes a component of friction. can i take hydroxyzine with adderallWebAnswer: No. Workdone in reversible is always more than the workdone in irreversible. The reason is the system has to work against the gradual higher external pressure in reversible condition. Whereas the external pressure is constant, no rising in irreversible condition, hence work is less. can i take hydroxyzine and melatoninWebirreversible process: 1 n any process that is not reversible Antonyms: reversible process any process in which a system can be made to pass through the same states in the reverse … fivem qb house script
