____ A substance underwent condensation during which its temperature changed 5 K.

____ A 24 N brick was fully submerged in water. The buoyant force on the brick was 15 N. As a direct result, the brick sank.

____ Last Wednesday, the Sun heated the Moon via conduction.

____ The temperature inside a physics laboratory chamber was measured to be 18 °F.

Explanation / Answer

'A 31 L container displaced 34 L of water when partially submerged' is impossible because the volume of the liquid displaced always equal to the volume of the container

'A substance underwent condensation during which its temperature changed 5 K' is impossible because condensation is a phase transition which will always occur at constant temperature 'Last Wednesday, the Sun heated the Moon via conduction.' is impossible because for conduction two objects have to be in contact
'The temperature inside a physics laboratory chamber was measured to be 18 °F' is impossible because the temperature is very low
