What do you know about Charles' Law? Check all the statements that are true.
For a fixed mass of gas, at a constant pressure, the volume () is directly proportional to the absolute
temperature (1)
Using the example of the sealed cylinder above, the volume of gas at the start is recorded as 30 cm with
a temperature of 30°C. The cylinder is heated further till the thermometer records 60°C. The new volume
of the gas is 32.97 cm3
Heat energy is applied to a cylinder containing a specific volume of gas. The temperature of the gas
increases. The average velocity of the gas particles increases resulting in an increase in the rate of
collisions and the average force per collision. This produces a decrease in pressure inside the cylinder
According to the ideal gas law, increasing the volume of a closed reaction container decreases the thermal
energy because the pressure and collision frequency decrease.
There is no relationship between temperature and volume for gases.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
