A sample of O2 with an initial temperature of 50°C and a volume of 105 L is called 225.0°C the new pressure is 105 point4K PA and the new volume is 55.0 L what was the initial pressure of the sample

35.81 KPa

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Initial temperature (T1) = 50°C

Initial volume (V1) = 105 L

Initial pressure (P1) =?

Final temperature (T2) = 225.0°C

Final pressure (P2) = 105.4 KPa

Final volume (V2) = 55.0 L

Step 2:

Conversion of celsius temperature to Kelvin. This is illustrated below:

K = °C + 273

T1 = 50°C + 237 = 323K

T2 = 225.0°C + 273 = 498K

Step 3:

Determination of the initial pressure of the O2 sample.

The initial pressure of the O2 sample can be obtained by using the general gas equation as follow:

P1V1/T1 = P2V2/T2

P1 x 105/ 323 = 105.4 x 55/ 498

Cross multiply to express in linear form

P1 x 105 x 498 = 323x 105.4 x 55

Divide both side by 105 x 498

P1 = (323x 105.4 x 55) /(105 x 498)

P1 = 35.81 KPa

Therefore the initial pressure of the O2 sample is 35.81 KPa

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
