3. which equation shows the relationship between the kelvin and celsius temperature scales? k = 273 – °c k = °c + 273 k = °f + 273 k = °c + °f

Explanation:

The Kelvin (), is the unit of temperature of the scale created by the British physicist William Thomson (Lord Kelvin) in 1848, taking as a base the Celsius scale, establishing the zero point for this scale in the absolute zero which is in .

This was achieved by observing that when a gas cools, its volume decreases proportionally to its temperature. That is, for each degree of temperature that the gas decreases, its volume also decreases by a certain percentage.

After which, Kelvin made the calculations and it turned out that at a temperature of the volume of the gas would be zero (theoretically).

It should be noted that the Kelvin is the unit of temperature of the International System of Units and that although the scale starts at absolute zero (theoretical), in which no molecule should move, in reality it is not so, because according to quantum physics, at this temperature the molecules retain a residual movement.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
