Chapter 4, Problem 1DQ

What is the specific heat of a substance that requires 3500J in order to raise its temperatures from 10°C to 35°C when its mass is at 100 grams. Give the answer using units of K and kg. What does this result mean?

3.5 kilograms of water in a container have a pressure of 100 kPa and temperature of 150oC. What is the volume of this container? Please give your answer in m3. Use two decimal places in your final answer. Thanks

in your own words, what is the principle of convection and conduction in making squash soup?

According to​ Newton's law of​ cooling, the rate at which a body cools is proportional to the difference in temperature between it and the surrounding medium. Assuming​ Newton's law​ holds, how long will it take a cup of hot​ water, initially at 194°F, to cool to 100°F if the room temp is 67°F, if it cools to 140°F in 4 ​min? Round to two decimal places.

An eccentric chemistry professor (not mentioninn any names) stops in every day and orders 250 mL of sumatran coffee at precisely 95*C. He then adds enough milk at 10*C to drop the temperature of the coffee to 90*C.  Calculate the amount of milk (in mL) the professor must add to reach this temperature. (Assume coffee and milk have the same specific heat capacity: 4.186 J/g*C. Assume that they also have the same density: 1.0g/ml)

A steel plug has a diameter of 9.000 cm at 30  °C. At what temperature will it fit exactlyinto a hole of constant diameter of 8.998 cm? ⍺ = 11 x 10^-6/°C

A vertical glass tube of length L = 1.3m is half filled with a liquid at 18.7 ˚C. How much will the height of the liquid column change when the tube is heated to 31.8 ˚C? Take αglass = 1.46× 10-5/K and βliquid = 4.37× 10-5/K.

A particular pair of human lungs have a volume of 1.8 L when inflated. At this volume, the temperature inside the lungs is 98.7°F. If the temperature of the air outside the lung is 43.2°F, what volume of cooler outside air is being inhaled and warmed?   Round your answer to 2 decimal places.

In 1701, the Danish astronomer Ole Rømer proposed a temperature scale with two fixed points, freezing water at 7.5 degrees, and boiling water at 60.0 degrees. What is the boiling point of oxygen, 90.2 K, on the Rømer scale?
