On molecular level what I causing the glaciers to melt
MakcuM [25]
Glaciers capture large amount of carbon dioxide from atmosphere. When concentration of carbon dioxide molecules in glaciers increase, then strength and fracture toughness of ice are decreased and <span>that make glaciers vulnerable to cracking and splitting into fragments.
</span>That is because hydrogen bonds between water molecules in glaciers is decreased under increasing concentrations of carbon dioxide who <span>competes with the water molecules connected in the ice crystal.</span>

A 30.g sample of Al(s) is heated to 50°C and placed in a calorimeter containing 150g of water at 20°C. As the system approaches
SpyIntel [72]

Energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.

<h3>Heat energy</h3>

Heat energy is a form of energy transferred from one body to another due to a temperature difference between the bodies.

Heat energy is also known as thermal energy.

In heat transfer, heat is transferred from a body at higher temperature to a body at lower temperature.

In the heat transfer between the heated aluminium and the water, the solid aluminium is at a higher temperature than the water, hence, heat energy is transferred from the aluminium to water.

Therefore heat energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.
