Two metal rods, one lead and one brass, are each clamped at one end (Fig. 6). At 0.0°C, the rods are each 40.0 cm long and are separated by 0.034 cm at their unfastened ends. At what temperature will the rods just come into contact and determine the change in length of the lead. (Assume that the base to which the rods are clamped undergoes a negligibly small thermal expansion.) 0.034 cm 40.0 cm 40.0 cm brass lead T = 0.0°C

How long would it take a persons with an average body (surface area of 1.8 m^2 and normal body temperature of 37◦C) to heat up a room (which hold 2700 moles of air) from 16.370◦C to 16.373◦C?
A cube of ice is taken from the freezer at -8.8°C and placed in a 104 g iron cup filled with 279 g of water. Both the water & the cup are at 23.9°C. Eventually the system reaches thermal equilibrium at 12.4°C. Determine Qcup, Qwater (for the water initially in the cup), Qice, & the mass of the ice.Qcup = Qwater = Qice = mice =
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?

A certain amount of gas at 25.0°C and at a pressure of 0.650 atm is contained in a glass vessel. Suppose that the vessel can withstand a pressure of 2.00 atm. How high can you raise the temperature of the gas without bursting the vessel? In other words, at what temperature will the glass vessel shatter, in degrees Celsius.
Brass 0.030 m 5.0 µm Brass has linear thermal expansion coefficient a = 19 × 10-6rC . The picture shows a design defect in an electrical assembly: if the screw expands enough to touch the surface on the left, a dangerous short circuit will occur. The picture shows the assembly at 15°C. What is the maximum tempe ure the assembly can tolerate? 46.9°C 32.6°C 23.7°C 27.4°C 19.3°C
