Aman would like to study the heat transfer between ice, water and steam. if there is 2kg of ice at -18c, 10kg of water at 25c and 1kg steam at 100c. assume there is no heat loss to the surrounding. specific latent heat of fusion for water lf = 3.34 × 105 j kg-1, specific latent heat of vaporization for water lv = 2.26 × 106 j kg-1, specific heat capacity of ice is 2100 jkg–1k–1, specific heat capacity for water c = 4200 j kg-1 c-1.
(a) a minimal portion of water is added to melt all the ice. how many kg of water is
required?
(b) a minimal portion of steam is added to melt all the ice. how many kg of steam is required?
(c) what is the final temperature (c) when all the ice and water mix with each other?
(3 marks)
(d) what is the final temperature (c) when all the ice and steam mix with each other?
(2 marks)

as technology advances, new experiments often expose problems in accepted theories. c

-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

hope this

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
