Agas initially at stp is changed to 248 k. calculate the final pressure of the gas.

The final pressure of the gas at 248 K is 0.908 atm

Explanation:

              At standard temperature and pressure, temperature of 0 Celsius and pressure which is equal to the atmosphere, 1 atm.

= 0 Celsius

= 1 atm

Change in temperature causes a change in the pressure:  

                          =248K

                          =?

Calculating the pressure,   using the Gay-Lusaac's law:  

Convert the temperatures from Celsius to Kelvin:

                        =0 Celsius+273=273K

                        =248K

To find  :

  = = 0.908 atm

b. examine and describe cells

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
