Changing temperature, density and pressure occur when a chemical reaction.
the process must take place underground~ apex
Not enough pressure or temperature.
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).

It is the weight of the air itself that causes air pressure. Fluctuations occur due to changes in wind and temperature. We live in air pressure of about 15 pounds per square inch.
Because the conditions of temperature and pressure that occur in stars do not occur on earth
Not enough pressure or temperature.
The pressure is doubled (up to SP=760 Torr) and the temperature is halved (down to ST=273 K) as long as the volume (and amount of matter) is UNchanged!
it harms the environment. temperature changes and climate changes occur because of chemical weathering.
Temperature changes that occur without any heat addition or subtraction is defined as internal energy. Another term for this occurrence is adiabatic change.

it is hot in summer. nights are colder.
because atoms expands when temperature increases in result physical changes.
