An enthusiastic car owner checks his tire pressure religiously and makes note that his tire pressure is 220 kPa in 80 degrees Fahrenheit (26.7 degrees Celsius). A strong cold front comes in and later in the week the temperature has dropped to 36 degrees Fahrenheit (2.2 degrees celsius). How can the car owner use gas laws to calculate the new tire pressure (in kPA units)?

202 KPa

Explanation:

Step 1:

Data obtained from the question.

Initial Pressure (P1) = 220 kPa

Initial temperature (T1) = 26.7°C

Final temperature (T2) = 2.2°C

Final pressure (P2) =?

Step 2:

Conversion of the Celsius temperature to Kelvin temperature.

Temperature (Kelvin) = temperature (celsius) + 273

T1 = 26.7°C + 273 = 299.7 K

T2 = 2.2°C = 2.2°C + 273 = 275.2 K

Step 3:

Determination of the new pressure.

The new pressure of the tire can be obtained as follow:

P1/T1 = P2/T2

220/299.7 = P2/275.2

Cross multiply to express in linear form

299.7 x P2 = 220 x 275.2

Divide both side by 299.7

P2 = (220 x 275.2)/299.7

P2 = 202 KPa

Therefore, the new pressure of the tire is 202 KPa

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
