A steel beam being used in the construction of a skyscraper has a length of 34.000 m when delivered on a cold day at a temperature of 10.000°F. What is the length of the beam when it is being installed later on a warm day when the temperature is 94.000°F? (Give your answer to at least five significant figures.) m Need Help? Read It

By what length will a slab of concrete that is originally 18.4 m long contract when the temperature drops from 28.2°C to -8.68°C? The coefficient of linear thermal expansion for this concrete is 1.0 × 10-5 K-1. Give your answer in cm.

In an air conditioner, 12.65 MJ of heat transfer occurs from a cold environment in 1.00 h. (a) What mass of ice melting would involve the same heat transfer?              (b) How many hours of operation would be equivalent to melting 900 kg ofice?                                                                                                                    (c) If ice costs 20 cents per kg, do you think the air conditioner could be operated more cheaply than by simply using ice? Describe in detail how you evaluate the relative costs.

A steel bar and brass bar have the exact same length of 1.8000 m at -15.00 deg C. The coefficient of linear expansion for steel is 1.2x10^-5 per deg C, the coefficient of linear expansion for copper is 2x10^-5 per Deg C. What is the difference in length between the two bars if the temp increases to 40 deg C? Express in mm.

A rubber ball of radius 2.12 m and emissivity 0.940 is heated to 128°C. HINT (a) Convert the given temperature to Kelvin. (Enter your answer to at least three significant figures.) K (b) What is the surface area (in m2) of the ball? m2 (c) If the ambient temperature is 24.0°C, what net power (in W) does the ball radiate? W

When the indoor temperature of a house is 25°C and the outdoor temperature is -8°C, the inside and outside surfaces of the glass are measured to be 21.4°C and 18.1°C.  If the glass has an area of 3.06 m2 and a thickness of 6.23 mm, what is the rate of heat (in W) lost though the window [round your final answer to zero decimal places]? {kglass = 0.78 W/m∙K}

The density of lead is 1.13 x 104 kg/m3 at 20.0°C. Find its density (in kg/m³) at 118°C. (Use a = 29 × 10-6 (°C)-1 for the coefficient of linear expansion. Give your answer to at least four significant figures.) HINT 1.12 kg/m3 Need Help? Read It Watch It S. 93% 4 A O E a 4 7:45 PM 12/4/2021 55°F

An iron rod with an initial length of 13.65 m has its temperature raise from 10°C to 31.74°C. If an iron has a coefficient of thermal expansion of 12 times Fr..10 to 6th power 1/Celsius what is the changing in the length of the rod?

Thermal energy is added to 180 g of water at a constant rate for3.5 min, resulting in an increase in temperature of 12 C°. What isthe heating rate, in joules per second?

A bubble of air is rising from the sea floor, from a depth of about 500 m. At this depth the pressure is 5.1*106 Pa (about 50.3 atm) and is at a temperature of about 7.0° C. It rises to the surface with the atmosphere, at a temperature of 20° C. If the bubble is observed to have a volume of 4 cm³ at the surface, what was its volume at the sea floor? Assume the number of moles of gas in the bubble is constant. B.
