The body uses energy to break chemical bond(takes energy). When a bond forms, energy is released(like magnet) in the form of Kinetic Energy. Bonds are being broken & formed in your body at the same time(series of chemical reactions).
Yes the movement of land forms is called the movment of plate tectonics. :) plz thnk me
Explanation:
sulphur has a low melting point.
sulphur has a low boiling point thus it can be extracted by pumping hot water which turns it ito solution form
Answer:
None of the above
Explanation:
Work is defined as the force that moves an object through a particular distance:
Workdone = force x displacement
At constant velocity, the force on a body is zero because such a body is not accelerating.
Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.
From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.
Answer:
The particles move faster, and their average kinetic energy increases.
Explanation:
When the temperature of gases increases the reaction rates will increase. Molecules of gases will be furnished with higher kinetic energy. Kinetic energy is directly proportional to temperature. Increase in temperature causes the frequency of ordinary collisions and effective collisions per unit time to increase. This leads to a surge in kinetic energy too.
