The molar heat capacity of a diatomic molecule is 29.1 mol. Assuming the atmosphere contains only nitrogen gas and there is no heat loss, calculate the total heat intake (in kJ) if the atmosphere warms up by 3.0°C during the next 50 years. Given that there are 2.8 x 1020 moles of diatomic molecule present, how many kilograms of ice (at the North and South Poles) will this quantity of heat melt at 0° C? (The molar heat of fusion of ice is 6.01 kJ/mol.) Total heat intake: х 10 |kJ Ice melted: x 10 kg
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.
