Liquid nitrogen has a boiling point of – 195.81°C at atmospheric pressure. Express this temperature (a) In degrees Fahrenheit and (b) In kelvins.

Liquid nitrogen has a boiling point of−190.52◦C at atmospheric pressure.Express this temperature in degreesFahrenheit.Answer in units of ◦F Express this temperature in Kelvin.Answer in units of K.

In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula. F = 1.8C + 32 Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula. K = C + 273.15 (a) Calculate that value.K(25) = (b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins. C = (c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins. F =  (d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?

Internal human body temperature is often stated to be normal at 98.6°F. What is this temperature on the Celsius and Kelvin scales? (b) Gallium boils at 2205°C. What is the corresponding temperature in the Fahrenheit and Kelvin scales? (c) The boiling point of liquid nitrogen is 77.0 K. What is corresponding temperature in the Fahrenheit and Celsius scales?

A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).

A machinist wishes to insert an iron rod with a diameter of 9 mm into a hole with a diameter of 8.998 mm. By how much would the machinist have to lower the temperature (in Celsius) of the rod to make it fit in the hole?

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14 = Cwhere C is a constant. Suppose that at a certain instant the volume is 670 cubic centimeters and the pressure is 99 kPa and is decreasing at a rate of 7 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm3 min (Pa stands for Pascal -- it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals. )
