The temperature 17
The temperature was -5 Celsius at 6 AM. It increased by a speed of three degrees every hour for six hours. The temperature then increased 1 1/2° every hour for five hours. What was the temperature at 5 PM?
When Joe
When Joe went to work at 6 AM, the outside temperature was 3 degrees Celsius. The weather worsened during the day, and by 3 PM, the temperature had dropped 5 degrees. What was the temperature at 5 PM?
An experiment 2
The temperature of a substance in an experiment changes by -8.7°F from 10 AM to 1 PM. At 5 PM, the temperature is 33.5°F, which is 2/3 of what it was at 1 PM. What was the temperature of the substance at 10 AM?
Change per hour
On Sunday, the temperature was 63 degrees at 2 PM. The temperature was then 72 degrees at 5 PM. What is the rate of change per hour?
Temperatures
Temperatures in degrees Fahrenheit and Celsius are related by the rule F = 1.8C + 32. What is the temperature in degrees Celsius if it is 50°F?
The temperature 16
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 level
The temperature 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.
Temperature up and dowm
The temperature is 19.4°C at 6 AM. Between 6 AM and noon, it rises by 3.8°C. Between noon and 6 PM, it falls 2.5°C. What is the temperature at 6 PM?
The temperature 13
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.
Now is
Now it is 5°C in the morning. What will the temperature be if i. It rises by 12°C ii. It falls by 15°C
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?
Thermometer 48543
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. 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 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
