Question

Transcribed Image Text:The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P.
A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a
volume of 120 liters. Find the pressure if the volume is decreased to 90 liters and the temperature is
increased to 350 degrees K.
Round your answer to two decimal places.
The pressure is Number

- Please help me with this question and explain it. Thank you!arrow_forwardIf a 5 m3 of gas initially at STP is placed under a pressure of 3 atm, the temperature of the gas rises to 17◦C. What is the volume now? Calculate to 2 decimals.arrow_forwardAn atom of neon has a radius Ne-38. pm and an average speed in the gas phase at 25°C of 350.m/s. Suppose the speed of a neon atom at 25°C has been measured to within 0.10%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of "Ne and round it to 2 significant figures. For example, if the smallest box the atom could be in turns out to be 42.0 times the radius of an atom of neon, you would enter "42.Ne" as your answer. [arrow_forward

(Assume the helium and air to be at 0°C and 1 atm.)Answer in Narrow_forwardThe pressure, volume, and temperature of a mole of an ideal gas are related by the equation PV = 8.31T, where P is measured in kilopascals, V in liters, and T in kelvins. Use differentials to find the approximate change in the pressure if the volume increases from 10 L to 10.6 L and the temperature decreases from 335 K to 330 K. (Note whether the change is positive or negative in your answer. I Round your answer to ti decimal places.arrow_forwardTwo containers of equal volume each hold samples of the same ideal gas.

- A container of gas holds 0.74 moles of neon gas. If the volume of the container is 11.8 liters and the pressure inside is 1.97 atm, what is the temperature (in K) of the gas?arrow_forwardThe pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an ideal gas are related by the equation PV = 8.317. Find the rate at which the volume is changing when the temperature is 325 K and increasing at a rate of 0.05 K/s and the pressure is 29 and increasing at a rate of 0.07 kPa/s. Please show your answers to at least 4 decimal places. dV dt L/sarrow_forwardAccording to the Ideal Gas Law, PV = kT, where P is pressure, Vis volume, T is temperature (in Kelvins), and k is a constant of proportionality.
