Which of the following statements about vacuum gauges are correct? Statement 1: Thermal vacuum gauges sense the cooling effect of a heated filament. Statement 2: Thermal vacuum gauges designed to measure high pressures.

Correct Answer: True, False
The vacuum gauges designed to measure very low pressures or in a vacuum.The vacuum gauges sense the cooling effect of a heated filament on the gases in the vacuum chamber being measured. It consists of heated thin wire. These resemble as thermal flow meters, where heated wire is placed into the flow steam and infer the flow by measuring the speed with which heat is dissipated. The vacuum gauges sense the cooling effect of a heated filament on the gases in the vacuum chamber being measured.

Land masses are heated and cooled much faster than water bodies. Identify the true statements in this regard:
I. Land gets heated by conduction
II. Water has higher specific heat
III. Only the surface layers of water are heated
IV. Water gets heated by convection

Simple air cooling system gives maximum cooling effect on ground surface whereas regeneration cooling system has more effect during high speeds.

The temperature of a heated metal filament depends on the gas pressure since the gas molecules could conduct heat from the filament.

Cold cathode ionization vacuum gauges are more accurate than hot cathode ionization vacuum gauges.
