A constant volume thermometer consists of a rigid bulb and a pressure gauge. To obtain accurate results, this thermometer must be calibrated at a known pressure and temperature. Once this is done, the bulb is sealed off from the atmosphere. The volume and number of moles of gas can no longer change and the temperature is calculated from the pressure measurement * 25% Part(a) A particular constant volume thermometer is calibrated by opening it to the atmosphere while the bulb is in a bath of boiling water. Enter an expression for the temperature of the thermometer in degrees Celsius, in terms of its pressure, P. in atmospheres 779)- 37.15 1CP). 27315 X Atep Remain * 25%

Part(b) When the constant volume thermometer that was calibrated as described in part(a) is used to measure a temperature, it shows a pressure of 10.95 atm. What temperature is it indicating, in degrees Celsius?

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k

How are positive ions different from neutral atoms

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
