Temperature remains constant during the change in phase (physical state).
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
The temperature remain constant during a change of phase.
Mixing BaCl2 and Epsom salt would be considered a physical change. This is because no new substances are formed during the process, only a physical mixing of the two compounds occurs.
They can be reversed by physical changes...
it is -220 digrees during the night and it is normally -270 during the nightbut the hottest it can get is-84 digreesyou tell me!
during a lighting storm the weather is normally cold
The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.
Sweating usually starts during physical activity when your body temperature rises and needs to cool down.
its normally like 60s during the day but it gets down to the 30s at night
To breathe normally and effectively during physical exercise, focus on taking deep breaths in through your nose and out through your mouth. Try to maintain a steady rhythm and avoid shallow breathing. This will help deliver more oxygen to your muscles and improve your performance.
Body temperature rises after exercising because the muscles have been heated up. This is what burns calories and it should even out after about 30 minutes.
