Can be used to heat a large amount of liquid the heat from the sun (solar panels) or nuclear power or , in the volcanic areas, the natural heat can be used.
The answer is sublimation.
Sublimation is the chemical process whereby a solid turns into a gas without first becoming a liquid.
The word sublimation comes from the Latin word sublimare which means "raised to a higher status."
Examples of sublimation include surface layer of snow and ice turning into steam or fog without melting and dry ice which is the solid form of carbon dioxide which also undergoes sublimation.
The low temperature and sublimation makes dry ice an effective coolant or cooling agent . One of its main advantages is that it has a lower temperature than water ice and also does not leave any residue.
Answer:
I think its False
Explanation:
ozone layer surroundes the atmosphere and traps the heat
The energy release when dissolving 1 mol of NaOH in water is 445.1 kJ
the mass of NaOH to be dissolved is 32.0 g
The number of NaOH moles in 32.0 g - 32.0 g / 40 g/mol = 0.8 mol
the energy released whilst dissolving 1 mol of NaOH - 445.1 kJ
when dissolving 0.8 mol - the energy released is 445.1 kJ/mol x 0.8 mol
therefore heat released is - 356.08 kJ
answer is -356.08 kJ
Answer:
B. 10 mL of Cabr2(aq) at 35 degrees celsius
Explanation:
The colder something is the more the atoms are compressed together; atoms can't move as much. 35 degrees is the warmest option, so it makes the most sense.
