If you shot a bullet at water, is there an angle at which the bullet would bounce off instead of just go through?
Olivia AskewNo, the bullet would break hydrogen bonds and the water molecules would slide around it because the force with which it struck the water would be much greater than the surface tension of the water.

Isabella AlvarezYes, there is an angle at which a bullet can bounce off the surface of water instead of penetrating it. This angle is known as the critical angle and depends on various factors including the velocity of the bullet and the surface tension of the water.

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 #4 L# and holds #2 mol# of gas. If the container is expanded such that its new volume is #12 L#, how many moles of gas must be injected into the container to maintain a constant temperature and pressure?
- A container with a volume of #"16 L"# contains a gas with a temperature of #"180 K"#. If the temperature of the gas changes to #"360 K"# without any change in pressure, what must the container's new volume be?
- If #18 L# of a gas at room temperature exerts a pressure of #15 kPa# on its container, what pressure will the gas exert if the container's volume changes to #27 L#?
- A container with a volume of #17 L# contains a gas with a temperature of #290^o C#. If the temperature of the gas changes to #580 ^o K# without any change in pressure, what must the container's new volume be?
- Water squirts from a syringe at a speed of 35 m/s. the diameter of the opening is .004 centimeters. what is the pressure difference in pascals between the water inside the syringe and the air outside? (assuming the syringe is horizontal and that the velocity inside is zero)
