Answer all the following questions

Question 1 [1 point]I Ignoring the heat added for the moment. if a gas does 855 J of work on Its surroundings, would that cause an Increase or decrease in the internal energy.r of the gas?{ 0 Internal energy becomes zero 0 Decreases O No change takes place 0 Increases Question 2 (1 point} Heat flows into a gas in a piston and the gas performs some work on its surroundings. The amount of work done is less than the heat added. In this situation, O the internal energy of the gas did not change. 0 the gas experienced a phase change. 0 the internal energy of the gas decreased. 0 the internal energy of the gas increased. 0 energy is not conserved and so it cannot happen. Question 3 (1 point) Which object is hotter? O Object 1 at T = 09 C O Object 2 at T = 09 F O Object 3 at T = OK Question 4 (1 point) Work of 1,742 J is done by stirring a perfectly insulated beaker containing 75 g of water. The specific heat capacity of water is 4186 J / kg"C. Calculate the change in the temperature of water in units of degree centigrade (be accurate to 4 decimal place) . Your Answer: Answer Question 5 (1 point) The volume of an ideal gas is increased from 0.4 m to 2.5 m while maintaining a constant pressure of 3.501 Pa (1 Pa = 1 N/m ). Calculate the amount of work in J done by the gas during the expansion. Keep one decimal place. Your Answer:Question 6 (1 point) If 849 cal of heat is added to 105 g of water initially at a temperature of 18 "C, what is the final temperature of the water in "C to 2 decimal places? Your Answer: Answer Question 7 (1 point) How much heat in units of cal (with 1 decimal) must be added to 123 g of ice at 0"C to melt the ice completely? The latent heat of fusion of ice is 80 cal/g. Your Answer: Answer Question 8 (1 point) Calculate the amount of heat in units of cal that must be removed from an 725-g block of aluminum to lower its temperature from 160"C to 40"C. The specific heat capacity of aluminum is 0.215 cal/g."C.round your answer to the nearest exact number. Your Answer: AnswerAnswer Question 9 (1 point) 922 calories of heat are added to a gas. In addition, the gas expands and does 400 joules of work on its surroundings. What is the change in the internal energy of the gas in calories? (be accurate to 2 decimal places) Your Answer: Answer Question 10 (1 point) The volume of an ideal gas is increased from 0.6 m to 2.5 m while maintaining a constant pressure of 3600 Pa (1 Pa = 1 N/m ). If the initial temperature of the ideal gas is 416 K, calculate the final temperature. in Kelvin to one decimal place. Your
