This is urgent! Please answer with the correct answer and fast! I made a thermometer which measures temperature by the compressing and expanding of gas in a piston. I have found that, at 1000 C, the volume of the piston is 20 L. What is the temperature (in either K or C) outside if the piston has a volume of 15 L?

How many moles are in 43.9 l of oxygen

If a simple machine aduces the strength of a force, what must be increased? the speed of the input force the work the simple machine performs the size of the simple machine the distance over which the force is applied

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
