The temperature on a warm summer day is 95°F. What is this temperature: a. in degrees Celsius? b. on the absolute (Kelvin) scale?

You happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.

At high noon, the Sun delivers 990 W to each square meter of a blacktop road. What is the equilibrium temperature of the hot asphalt, assuming its emissivity e = 1? (σ = 5.67 × 10−8 W/m2?K4) . a. 364°C b. 637°C c. 90.5°C d. 181°C e. 136°C

You have 1.3 liters of water in an insulated container at 14.8 °C.  You use an immersion heater to add 20.2 Joules of heat to the water. What is the final temperature of the water in °C?

A copper kettle weighs 1.03 kg. (The specific heat of copper is 0.384 J/g·°C)   1. What is the heat capacity (in J/°C) of the kettle?     2. How much heat (in J) is required to increase the temperature of this kettle from 23.1°C to 98.9°C?      3. How much heat (in J) is required to heat this kettle from 23.1°C to 98.9°C if it contains 1.30 L of water (density of 0.997 g/mL and a specific heat of 4.18 J/g·°C across the temperature range)?

P3. After a particularly cold night, Alice leaves a tub of water outside. You may consider the ground and air to have temperatures of T. = -10°C and T = 10°C respectively. How thick is the layer of ice that forms at the bottom of the tub of water, after the tub has been left outside for a long time? The tub of water initially has a layer of water of thickness họ = 10 cm. You may assume that the ground and air remain at a constant temperature throughout, and that the side lengths of the tub a, b > ho, i.e. the heat conduction is one- dimensional. Density of ice and water are Pice = 920 kg/m³ and Pw = 1000 kg/m³. Ice and water have thermal conductivities of kice = 2.22 WK-1m-1 and kiw = 0.556 W K-1m-1.
