# why do some things sink?

##
the weight of the body applies downward force on the water molecules

and according to newton's 3rd law of motion there is a equal opposite reaction force

so the both get balanced out so now the only force acting on the object is the upthrust so there's no downward force so why do some things sink?

The object which is more dense than the fluid sinks in that fluid.

This is related to Archimedes principle.

A body experiences buoyant force when submerged in a liquid.

because of the fluid, which is equivalent to the fluid's weight that it has displaced.

When an object's weight surpasses the buoyant force, the

item submerges in that liquid.

Objects sink if their density is greater than the density of the fluid they are placed in.

Some things sink due to their density being greater than the density of the fluid they are placed in. This causes them to displace a volume of fluid equal to their weight, resulting in a net downward force and causing them to sink.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A container has a volume of #2 L# and holds #1 mol# of gas. If the container is expanded such that its new volume is #4 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
- The gas inside of a container exerts #15 Pa# of pressure and is at a temperature of #220 ^o K#. If the temperature of the gas changes to #20 ^oC# with no change in the container's volume, what is the new pressure of the gas?
- A container with a volume of #5 L# contains a gas with a temperature of #360^o K#. If the temperature of the gas changes to #640^o K# without any change in pressure, what must the container's new volume be?
- The gas inside of a container exerts #12 Pa# of pressure and is at a temperature of #30 ^o K#. If the temperature of the gas changes to #20 ^oK# with no change in the container's volume, what is the new pressure of the gas?
- If #7/6 L# of a gas at room temperature exerts a pressure of #9 kPa# on its container, what pressure will the gas exert if the container's volume changes to #5/4 L#?
