The temperature at 6 AM was 21 degrees Fahrenheit. By noon, it had dropped to 32 degrees Fahrenheit. What was the temperature at noon? - The temp range What is the range in temperatures if the high temperature is 67 degrees Celsius and the low temperature is -25 degrees Celsius?
- Ice to boiling water
Calculate the heat needed to convert 5kg of ice at a temperature of -5°C to water with a temperature of 100°C. c (water) = 4200 J/°C/kg, c (ice) = 2100 J/°C/kg. The mass group heat of solidification of water is l = 334 kJ/kg. Calculate the heat that 1k g - The temperature 14 The temperature is 12°C lower than 4 hours ago. a. What is the average temperature change per hour? b. Write an integer equation for the situation.

The temperature in Toronto at noon during a winter day measured 4°C. The temperature started dropping 2° every hour. Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3°C? - The temperature 12 The temperature of a liquid was 25°C before being warmed at a rate of 10°C per minute for 5 minutes. It was then cooled at 3.5°C per minute for 6 minutes. What was the temperature of the liquid after cooling?
- Lower temperature The temperature level of the liquid in a thermometer is 24.32°C lower than the boiling point of water. What is the thermometer reading? Show your answer by drawing and shading the thermometer.
- Lead melt Find the heat needed to melt an object made of lead weighing 250g and an initial temperature of 35°C. Lead melts at 327°C at normal pressure. Mass heat capacity of lead c = 129 J/kg • K and mass latent heat of lead lt (t is the subscript) = 22.6 kJ/kg.

- Thermometer
Immerse a thermometer with a heat capacity of 2.0 J/K 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 tempe - 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 - 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 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
