- Air thermics
In a cylinder with volume V0 is enclosed air. The temperature of the air is T and the pressure is p0. While maintaining a constant temperature, first the air is compressed by a piston to one sixth of its volume. Then, after very rapid opening and closing - There
There is 5 l of water with a temperature of 20 °C in the bucket. We add 3 liters of hot water. The resulting temperature will be 30 °C. What was the temperature of the hot water? - Temperature rise fall
In the morning, the thermometer showed -7 °C. The temperature rose by 4 °C, then rose again by 9 °C, fell by 2 °C, rose by 3 °C, fell by 6 °C, and finally fell again by 5 °C. What is the final temperature? - The temperature 11
The temperature on Sunday was 4 °C. On Monday it dropped by 8 °C, and on Tuesday it dropped by twice as much as on Monday. What was the temperature on Tuesday? - Thermometer
A thermometer with a heat capacity of 2.0 J/K is immersed in 67.0 grams of water. Before immersion, the thermometer reads 17.8 °C. After reaching thermal equilibrium, the temperature is 32.4 °C. What was the temperature of the water before the measurement - Latent heat
How much heat is needed to take from 100 g of water at 20 °C to cool to the ice at -18 °C? Mass heat capacity c (ice) = 21 kJ/kg/°C; c (water) = 4.19 KJ/kg/°C and the mass group heat of solidification of water is l = 334 kJ/kg - Roxville
The temperature in Rockville decreased by 15 degrees in five hours. What was the average decrease in temperature per hour? Write your answer as an integer. - Heat transfer
We placed a lead object weighing 0.4 kg and 250 °C in 0.4 L water. What was the initial temperature of water t2 if the object's temperature and the water after reaching equilibrium was 35 °C? We assume that the heat exchange occurred only between the lead - Petra Petra likes to bathe in a bathtub with a water temperature of 38 degrees. She turned on the hot water set at 70 degrees and left for a moment. Before she returned, 40 liters of water flowed into the tub. How much water with a temperature of 22 degrees mus
- At noon 2 At noon, the temperature was 4 degrees Fahrenheit. At 6 pm, it was 10 degrees colder. What was the temperature at 6 pm?
- The aluminum An aluminium object weighing 0.80 kg at 250 °C is placed in 1.6 kg of water at 23 °C. What is the equilibrium temperature of the system? Assume that heat exchange occurs only between the aluminium object and the water. The specific heat capacity of alumin
- The bath The bath has water with a volume of 220 l and a temperature of 65 °C. Find the mass m2 of water at 15 °C to be poured, so the resulting temperature in the bath will be 40 °C. We neglect the heat exchange between water and the environment. Water
- Temperature drops If the temperature of a city drops 2° every day and increases by 3° every five days, how long does it take to drop to -15° from temperature +5°?
- Radiators
Calculate the radiator output if it has a thermal gradient (difference between inlet water and return temperatures) a) 5 °C b) 10 °C c) 15 °C d) 20 °C A heating water volume flow is 45 kg/h. How fast the water flows from the supply pipe to the radiator e) - Ground level The ground-level temperature in Helsinki is 20 °C lower than in London. The temperature in a basement flat in Helsinki is 5 °C below the temperature at ground level. If it is -29°c in the basement, what is the temperature in London?
- At midmorning The temperature at midmorning was 31 °C. Early in the evening, the temperature dropped by 5 °C. What was the resulting temperature?
- Weather
Weather. At 5:00 am, the temperature was 28 °C, and at noontime, it rose by 9 °C. By 4:00 PM, it dropped 3 °C; by nighttime, it was 4 °C less. What is the room temperature this time? - The bath Dad poured 50 liters of water at 60 °C into the tub. How much cold water must he add at 10 °C to obtain a bath that has a temperature of 40 °C?
- Water temperature mixing The mother prepared half a liter of cold water for the children to drink. It mixed water at 20 °C with 400 ml of cold water at 5 °C. What was the temperature of the prepared drink?
- Water temperature mixing John filled 2 liters of hot water at a temperature of 90 °C from a heater into a five-liter container. What temperature must the water that the container fills have a mixture temperature of 42 °C?
