1.3. A copper cylinder has a mass of 65.5 g and a specific heat of 0.092 cal/g·°C. It is heated to 85.5 °C and then put in 58.8 g of turpentine whose temperature is 23.5 °C. The temperature of the mixture was measured to be 45.9 C. Calculate the specific heat of the turpentine

Newton's Law of Cooling  The temperature of a cup of coffee t min after it is poured is given by the following equation where T is measured in degrees Fahrenheit. T = 65 + 90e−0.068t   (a) What was the temperature (in degrees Fahrenheit) of the coffee when it was poured? ____ °F (b) When (in minutes) will the coffee be cool enough to drink (say, 120°F)? (Round your answer to one decimal place.)  ______min

Calculate final temperature of 30 g of water heated with 2,780 J. The heat capacity of water is 4190 J/kg / C ◦ The initial temperature of water is 0 C ◦      Calculate to one decimal.

If a 5 m3 of gas initially at STP is placed under a pressure of 3 atm, the temperature of the gas rises to 17◦C. What is the volume now?  Calculate to 2 decimals.

A test tube contains 2.61x10-4 m3 of liquid carbon tetrachloride (β = 1240x10-6 (C°)-1) at a temperature of 64.0°C. The test tube and the carbon tetrachloride are cooled to a temperature of -13.0°C, which is above the freezing point of carbon tetrachloride. Find the volume of carbon tetrachloride in the test tube at -13.0°C.

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 21.3°C and 17.3°C.  If the glass has an area of 3.16 m2 and a thickness of 6.14 mm, what is the rate of heat (in W) lost though the window? {kglass = 0.78 W/m∙K}

The Specific Heat Capacity of Lithium is 3.56 J / g C. What is this Specific Heat Capacity using calories?
