When you first step outside on a cold day, your skin is 70° F (21 C). After you've been outside for a while, your skin cools to a temperature of 60° F (16 C). Use this fact to explain why you feel less cold after you've been outside for a while.

Arelyz and Hyeonggyun drop a 378.0-g piece of metal at 100.0°C into 447.0 g of water at 20.0°C. The final temperature of the system is measured to be 50.0°C. What is the specific heat of the metal in J/kgK, assuming no heat is exchanged with the surroundings or the cup containing the water? The specific heat of water is 4190 J/(kg K).

19. In a physics experiment, a 0.100 kg aluminum calorimeter cup holding 0.200 kg of ice is removed from the freezer, where both ice and cup have been cooled to -5.00 degrees Celsius. Next, 0.0500 kg of steam at 100 degrees Celsius is added to the ice in the cup. What will be the equilibrium temperature of the system after the ice has melted? (c_aluminum=920 J/kgC, ice melts at 0 degrees Celsius)    a. 28.1 degrees Celsius b. 31.4 degrees Celsius c. 33.3 degrees Celsius d. 35.5 degrees Celsius e. None of the above

A thermos contains m1 = 0.96 kg of tea at T1 = 32° C. Ice (m2 = 0.095 kg, T2 = 0° C) is added to it. The heat capacity of both water and tea is c = 4186 J/(kg⋅K), and the latent heat of fusion for water is Lf = 33.5 × 104 J/kg.  Part (a)  Input an expression for the final temperature after the ice has melted and the system has reached thermal equilibrium.   Part (b)  What is the final temperature in Kelvin?

A chunk of metal with a mass of 85.0 grams and a specific heat of 759 joules per kilogram·kelvin is heated to 78.9 degrees Celsius and placed in 122 milliliters of water (c = 4186 J/kg·K) at 18.6 degrees Celsius. What is the final temperature of the metal and water? Hint: The heat lost by the metal is gained by the water, so the sum of the heats is zero.

On a sunny day when the outside temperature is 34.0°C, a car parked in the sun is receiving 812 watts/m2 of incoming solar radiation (Insolation). Because the car radiates heat off of a greater surface area, the car in-turn radiates off heat at a rate of 169 watts/m². If the car is considered a perfect absorber and emitter of radiative energy, what will the equilibrium temperature inside the car be? °C
