The meteorological measurement showed the evening temperature at 18:00 at 21.3 degrees. At 21:00, the mercury on the thermometer stopped at 20.5 degrees. By how many degrees did the evening temperature drop in 3 hours?
- The temperature
The temperature at 1:00 was 10°F. Between 1:00 and 2:00, the temperature dropped by 15°F. Between 2:00 and 3:00, the temperature rose by 3°F. What is the temperature at 3:00? - Temperature 7595
Colorless liquid weighing m = 200 g is heated with constant stirring on a stove with power input P0 = 600W. 80% of the supplied energy is used to heat the liquid. Selected measured values of liquid temperature as a function of time are recorded in the t - 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 increase
Suppose the temperature at 9:am is 50 degrees. What is the temperature at 5:00 pm if the temperature increases by 4 degrees Fahrenheit each hour? - 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?

We heated water weighing 1 kg at 70 degrees in a kettle. C. In 5 min. What is the power consumption of the kettle? We do not take into account losses or boiling points. - Exponential warm
Suppose that a body with temperature T1 is placed in surroundings with temperature T0 different from that of T1. The body will either cool or warm to temperature T(t) after time t, in minutes, where T(t)=T0 + (T1-T0)e^(-kt). If we placed jello salad at 30 - Warmer weather
This morning it was -6 °C. What temperature did the thermometer show yesterday if it was three times warmer? - Temperature 4474
Mom is going to wash by hand in water that should be at 40°C. The tub already has 10 liters of water at a temperature of 12.3°C and can still hold 5 liters. What temperature should the water be allowed to be? - Daily temperature
The average daily temperature measurements for one week every day at the same hour was -2.8 °C. We measured all temperatures on different days are different. The highest daily maximum temperature was 2.4 °C, and the lowest was -6 °C. Determine the options
- 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? - 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? - 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. - Daily average
Calculate the average temperature during the day, when 14 hours were 24 °C and 10 hours was 14 °C.
