Hypothesis: if a fixed amount of gas is heated,
then the volume will
because
the heat will cause the molecules of gas to move

If fixed amount of gas is heated then the volume will increase because the heat will cause the molecules of gas to move freely and increase the kinetic energy.

Explanation:

If fixed amount of gas is heated then the volume will increase because the heat will cause the molecules of gas to move freely and increase the kinetic energy.

According to the Charle's law

The volume of given amount of gas is directly proportional to the temperature at constant pressure and number of moles of gas.

Mathematical expression;

V ∝ T

V = kT

V/T = k

if volume is changed from V1 to V2 and temperature change from T1 to T2 then,

V1/T1 = k      V2/T2= k

V1/T1 = V2/T2

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
