The density of liquid oxygen at its boiling point is 1.14 kg/Lkg/L , and its heat of vaporization is 213 kJ/kgkJ/kg . How much energy in joules would be absorbed by 3.0 LL of liquid oxygen as it vaporized? Express your answer to two significant figures and include the appropriate units. ------ Water's heat of fusion is 80. cal/gcal/g , and its specific heat is 1.0calg⋅∘Ccalg⋅∘C . Some velomobile seats have been designed to hold ice packs inside their cushions. If you started a ride with ice packs that held 1300 gg of frozen water at 0 ∘C∘C , and the temperature of the water at the end of the ride was 32 ∘C∘C , how many calories of heat energy were absorbed? Express your answer to two significant figures and include the appropriate units. ---- Water's heat of fusion is 80. cal/gcal/g , its specific heat is 1.0calg⋅∘Ccalg⋅∘C, and its heat of vaporization is 540 cal/gcal/g . A canister is filled with 330 gg of ice and 100. gg of liquid water, both at 0 ∘C∘C . The canister is placed in an oven until all the H2OH2O has boiled off and the canister is empty. How much energy in calories was absorbed? Express your answer to two significant figures and include the appropriate units.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
