In the morning, the thermometer showed -7 °C, then 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. The temperature dropped eight °C on Monday and twice as much on Tuesday. What was the temperature on Tuesday? - Thermometer
Immerse a thermometer with a heat capacity of 2.0 J. K-1 in water weighing 67.0 grams. Before water immersion, the thermometer showed a temperature of 17.8 degrees Celsius. After reaching equilibrium, the temperature is 32.4 degrees. What was the water te - 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) = 21kJ/kg/°C; c (water) = 4.19 KJ/kg/°C and the mass group heat of solidification of water is l = 334kJ/kg

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 o - 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
We placed the aluminum object with a weight of 0.80 kg and a temperature of 250°C in the water with a weight of 1.6 kg and a temperature of 23°C. What is the system temperature after reaching equilibrium? We assume that the heat exchange occurred only bet
- 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. The mass - 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) DN1 - Temperature 38971
A zinc body has a volume of 20 dm³. What heat is needed to warm it from a temperature of 25 to 100 degrees Celsius? What is this body's heat capacity C (unit J/K)? - 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
