What is the initial temperature (°C) of a system that has the pressure decreased by 10 times while the volume increased by 5 tim
horrorfan [7]

Answer:

27°C or 300K

Explanation

We were told that the pressureof the system decreased by 10 times implies that P2= P1/10

Where P2=final pressure

P1= initial pressure

Wew were also told that the volume of the system increased by 5 times this implies that V2= 5×V1

Where T2= final temperature =-123C= 273+(-123C)=150K

T1= initial temperature

But from gas law

PV=nRT

As n and R are constant

P1V1/T1 = P2V2/T2

T1= P1V1T2/P2V2

T1=2×T2

T1=2×150

T1=300K

=300-273

=27°C

the initial temperature (°C) of a system is 27°C

A ballerina weighs 103 lbs and is up on her toes with only 10.0 cm2 of her slippers in contact with the floor. What pressure is
Ahat [919]

Answer:

A

Explanation:

1 lb = .453 kg...so...103 x .453 = 46.72 kg  

you then multiply that by the force of gravity which is 9.8(m/s2)...so...  

46.72 x 9.8 = 458 newtons(kg x m/s^2), which is the force.  

pressure (in pascals) = Force(N) / Area (m2)  

we need to convert 10cm2 to m2 which = .001m^2  

458 / .001 = 458000 = 4.58 x 10^5 Pa

A sample of gas (1.3 mol) occupies __________ l at 22 °c and 2.5 atm.
Furkat [3]
To answer this question, you just need to put all the variable into <span>PV = nRT formula. In this case, the pressure(P) is 2.5 atm, the number of molecule(n) is 1.3 mol, the temperature(T) is 22 celcius= 295.15 kelvin.
Then the volume should be:

</span><span>PV = nRT
</span>2.5 * V = 1.3 * <span>0.08206* 295.15
</span>V= 12.59L
