1atm is equal to
Correct answer: D. all of the above
- A. 760 torr
- B. 760 mmHg
- C. 101.3 kPa
- D. all of the above
Explanation
The standard atmospheric pressure is 1 atm = 760 torr = 760 mmHg = 101.3 kPa. Choosing only 760 mmHg or 101.3 kPa gives an equivalent value, but misses that all three listed values represent the same pressure.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
