How to calculate mass with volume temperature and pressure?
You cannot. If you know the volume, temperature and pressure of a pencil, you will be no closer to knowing its mass!
What is the independent variable between temperature and volume?
pressure
How will volume of a balloon change if pressure remains constant but temperature increases?
The volume will increase in proportion to the increase in absolute temperature.
The volume of a gas depends upon its?
density, temperature and pressure
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)
