Question 4. A 5.0 kg block of aluminium is heated from 20°C to 90°C at atmospheric pressure. Find (a) the work done by the aluminium, (b) the amount of energy transferred to it by heat, and (c) the increase in internal energy.
An unknown substance has a mass of 0.250 kg and an initial temperature of 90.0°C. The substance is then dropped into a calorimeter made of aluminum containing 0.300 kg of water initially at 25.0°C (assume the water and calorimeter start in thermal equilibrium). The mass of the aluminum container is 0.200 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32.0°C. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance. The specific heat of water is 4186 J/(K*mol) and aluminum is 900 J/(K*mol).
An ideal gas initially at 300 K undergoes an isobaric expansion at 2.50kPa. If the volume increases from 1.00 m3 to 3.00 m3 and 12.5 kJ is transferred to the gas by heat, find the change in thermal energy and its final temperature.
An ISOBARIC process is one in which the PRESSURE REMAINS CONSTANT. Answer the following questions regarding the isobaric process.
An object of mass 7.90 kg falls through a height of 40.0 m and, by means of a mechanical linkage, rotates a paddle wheel that stirs 0.620 kg of water. Assume that the initial gravitational potential energy of the object is fully transferred to thermal energy of the water, which is initially at 13.0°C. What is the temperature rise of the water?
