Boiler heated water at the rate of 6°c per minute for 14 minutes. It then cooled at the rate of 8°c per minute. What would be its temperature after 24 minutes if its original temperature was 40°c? - The temperature 28
The temperature rose 14°C in 3 1/2 hours. At what rate, in degrees per hour, did the temperature rise? - Temperture drops
In Alaska, the temperature drops a total of -18 degrees over a three-day period. If the temperature drops at a constant rate, what is the change in temperature per day? - The temperature 20
The temperature is rising 4 degrees each hour and is currently 62 degrees. How many hours before the temperature are at least 80 degrees? - 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? - 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? - 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 25901

A liquid is heated at a rate of 5 degrees Celsius per minute. If the temperature now is at 39 degrees Celsius, how long will the temperature be by 94 degrees Celsius? - Equal temperature
We measured the temperatures of the two cities at the same time. The temperature in town A was 60 degrees And rose at a constant rate of 2 degrees per hour. The temperature in city B was 40° and rose at a constant rate of 10° per hour. Find the time in ho - A cold front
At 1:00 PM, the temperature was 46 degrees. Then, a cold front moved in and decreased the temperature by 12 degrees per hour. The temperature at 6:00 PM = _____ degrees. - Temperature 7477
The pool with a length of l = 50 m and a width of s = 15 m has a depth of h1 = 1.2 m at the shallowest part of the wall. The depth then gradually increases to a depth of h2 = 1.5 m in the middle of the pool. = 4.5 m walls in the deepest part of the pool. - Temperature 5
The temperature outside starts at 0 Fahrenheit. Over time the temperature changes at a rate of -0.6 Fahrenheit per hour. How long will it take for the temperature to reach -4.5 Fahrenheit? - Trains for people
It is said that the train is synonymous to delay. Calculate the average travel speed by train long 85 km, with a regular train leaving at 7:00 and arriving at 8:18, but the train is late and has a departure at 8:10 and arrives at 9:27.
