Vacuum chambers are sometimes externally heated during the pumping process, what is a possible reason for this procedure? chamber walls require heating to decrease the pressure inside the vacuum chamber adsorbed gas particles are released from chamber walls when heated increasing gas temperature leads to faster gas particles which leads to faster pumping rate increasing gas temperature increases collision rate with walls leading to faster pumping rate Vacuum chambers are sometimes externally heated during the pumping process, what is a possible reason for this procedure? chamber walls require heating to decrease the pressure inside the vacuum chamber adsorbed gas particles are released from chamber walls when heated increasing gas temperature leads to faster gas particles which leads to faster pumping rate increasing gas temperature increases collision rate with walls leading to faster pumping rate
