According to KMT, if the temperature of a gas is increased, there will only be a constant pressure if the volume increases. If this occurs, there will be a decrease in the frequency of collisions with the container walls. What gas law is KMT explaining?

The gas law KMT is explaining is Charles' law

Explanation:

The gas law KMT is explaining is Charles' law. Charles' law states that " the volume of a fixed mass of a gas is directly proportional to the temperature provided that the pressure remains constant". This means that, at constant pressure, as the temperature of a gas increases, the volume increases. Also, as the temperature of a gas decreases, the volume decreases.

Mathematically,

V ∝ T (V varies directly with T)

Where V is the volume and T is the temperature.

We can then write that,

V = kT and

V/T = k

This means that

V1/T1 = V2/T2 = V3/T3 ...

Hence,

V1/T1 = V2/T2

This is the Charles' law equation.

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
