- If you pour 0.0100 kg of 20.0ºC water onto a 1.20-kg block of ice (which is initially at −15.0ºC ), what is the final temperature? You may assume that the water cools so rapidly that effects of the surroundings are negligible.Ice of mass 50.0 g at -10.0° C is added tp 200 g of water at 15.0° C in a 100 g glass container of specific heat 0.200 cal/g-C° at an initial temperature of 25.0° C. Find the final temperature of the system.A length of thin wire is placed over a block of ice (or an icecube) at 0°C. The wire hangs down both sides of the ice,and weights are hung from the ends of the wire. It is foundthat the wire cuts its way through the ice cube, but leaves asolid block of ice behind it. This process is called regelation.Explain how this happens by inferring how the freezingpoint of water depends on pressure.
- A high-pressure gas cylinder contains 50 L of toxic gas at a pressure of 1.5.107 N/m² and a temperature of 23 °C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature -78.5 °C to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? P: 9837079 Pa (b) What is the final pressure if one-tenth of the gas escapes? P 8853371 Pa (c) To what temperature must the tank be cooled to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)? T: 200.331 K (d) Does cooling the tank appear to be a practical solution to bring the pressure down and reduce the leak? Assume N, N2. Take into account the values calculatesd in parts (a) through (c). No ! No, that's only partially correctSuppose that 0.95 g of steam (aka gaseous water), initially at 100 °C, condenses on a 75.0 g block of iron that is initially at 22 °C. What is the final temperature of the combined system when thermal equilibrium is reached?What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.95-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 60.0°C? Assume any water turned to steam subsequently recondenses. kg
- One assistant poured 998.00 cm3 of liquid mercury into a 1000.00-cm3 -flask, when both the mercury and the glass were at 4.0 ◦C. The teacher, has asked you to determine the maximum temperature he can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows if mercury has a coefficient of volume expansion of 18.0 * 10-5 ◦C-1 and the glass of the flask has a coefficient of volume expansion of 1.8 * 10-5 ◦C−1.An insulated beaker of negligible mass contains 0.250 kg of water at a temperatureof 75.0◦C. How much ice at a temperature of 0.00◦C must be dropped in so the finaltemperature of the system will be 30.0◦C?The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature in degrees Celsius when 1.00 kcal of heat enters 1.50 kg of the following, originally at 22.5°C. (a) water (b) concrete (c) steel (d) mercury
- How much liquid water, initially at temperature 19.0°C, can a freezer rated at 350.0 Watts and with a COP of 5.30 cool and freeze into ice at 0.00°C in 30.0 minutes? Assume that all energy as heat removed from the appliance's cold compartment is removed from the water. Please enter the answer in units of kilograms [kg].a cup of coffee sits on a table in an insulated mug. to coool the coffee down a ice block is added. the inital mass of coffee in the mug is 90g. the intial temperature of the coffee is 90 degree celsius. the ice block has started to melt and is then put into the coffee. the ice melts and the new temperature of the cofee is 78 degree c and the new mass is 110g. the ice block (final-intital mass) is 20g. what are teh tempeartuare changes for the coffee and ice (started at 0 degree celsius) also if specific heat of water is used for both the coffee and ice waht is the heat energy lost by the coffee and the heat energy gained by the ice after it melted?I am stuck on this question i got for homework :( I got a final temperature as 150 degrees Celsius which not possible
