Described as below
Explanation:
If the air above the land is cold and the temperature of land or soil is warm this heated light air will rise upwards and cold and dense air mass will settle on the ground as a result of the amount of humidity in the air will increase. This phenomenon time may lead to the development of the front of warm and cold air also the formation of a cyclone takes place in a similar manner if it takes place in water. This could also create a temperature inversion type of conditions at night time. on average the earth temperature changes from 2-3 degrees per 100 meters in greater depths and increases from 1° to 5° C/100 m.Ответ:
Complete question is;
The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The specific heat capacity of a certain substance has been measured to be 3.52 J/g°C. Suppose 420.0 g of the substance is heated until the temperature of the sample has changed by 43.8 °C.
Write an equation that will let you calculate the last Q that was needed for this temperature change. Your equation should contain only symbols. Be sure to define each symbol.
Q = m•c•Δt
Q = 64753.92 J
Explanation:
We are given;
Mass (m) = 420 g
Change in temperature; (Δt) = 43.8 °C
Specific heat capacity (c) = 3.52 J/g °C
The last Q is simply the heat energy that caused that temperature change.
This is given by the formula;
Q = m•c•Δt
Plugging in the relevant values;
Q = 420 × 3.52 × 43.8
Q = 64753.92 J
