Water mixing
Find how many liters of water at 80 °C and 20 °C need to mix to get 30 liters at 60 °C.
Water mixing - tub
The tank has water with a volume of 300 liters and a temperature of 10 °C. Add water at a temperature of 90 °C until a temperature of 30 °C is reached. How many liters of warmer water do I need to add?
Water temperatures
To 25 liters of water at 50 °C, we add 15 liters of water at a different temperature. How many °C should the water be colder than 50 °C so that 40 liters of the water obtained has a temperature of 42.5 °C?
Freezer
The temperature is -8 degrees Celsius in the freezer. The outside temperature is 2 degrees Celsius. If we open the door, it takes one minute to change the temperature by one degree Celsius. How many minutes the temperature in the freezer will rise?
Electrics - conductor
The wire is 107 meters long at 0 °C, and at every temperature increase of 1 °C, the length increases by 0.15 mm per 1 m length of wire. Determine a function that represents the wire's overall length as a temperature function. What is the length of the wir
Thermometer
The thermometer showed 0 °C in the morning. Then, the temperature increased by 2 °C, again increased by 1 °C, decreased by 6 °C, and then decreased by 1 °C. Which terminal temperature thermometer shows?
Mine
In the mine, at depth 18 m is 12°C, and every 50 m, the temperature increases by 1°C. What is the temperature at a depth of 1615 m?
Water
Mix 58 l of water with a temperature of 81 °C, 10 l warm of 54 °C, and 41 l water of 67 °C. What is the temperature of the mixed water immediately after mixing?
Bath
There are 30 liters of hot water in the bath. Then we added 39 liters of cold water at a temperature of 19 °C and decreased the temperature of the water to 45 °C. What was the initial temperature of the hot water?
Trains for people
Trains are often associated with delays. Calculate the average travel speed of a train on a 85 km route if the scheduled departure is 7:00 and arrival is 8:18, but the train is delayed — departing at 8:10 and arriving at 9:27.
Daily average
Calculate the average temperature during the day if the temperature was 24 °C for 14 hours and 14 °C for 10 hours.
Extreme temperatures
The USA hit an extreme heat wave. Calculate the percentage of the air temperature change from normal summer temperature 25 °C to 38 °C.
Temperature calculus
Calculate the percentage of temperature stúpla if changed from 3°C to 7°C.
