What quantities does the combined gas law deal with?
pressure and volume
What is a mathematical unit rate?
A unit rate is a rate that has a denominator of 1. Examples of unit rates include unit cost, gas, mileage and speed
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
What gas law applies to the bends?
Henry's law is one of the gas laws, stating that the amount a gas dissolves in a given type and volume of liquid is proportional to the partial pressure of that gas. As pressure builds, more nitrogen and oxygen gets absorbed by the blood in the body, and it tends to get absorbed faster than it gets released, meaning that when you resurface and the pressure declines, the gas in the blood is still increased.
If a certain gas occupies a volume of 1.3 liters at 300 K and a pressure of 18 newtons what is the volume at 340 K and a pressure of 24 newtons?
The combined gas law say PV/T=k. 1.3*18/300=k=V*24/340 V=1.3*18*340/(300*24)=11.05 litres
