When ice melts, it absorbs as much energy as it would take to heat an equivalent mass of water by 80 ° C.

When the blade of an ice skate passes over the ice, the ice undergoes two kinds of changes in its physical state and a change in temperature due to kinetic friction and the heat of melting.

When an electron absorbs energy either from light ( photons ) or heat ( phonons ), it receives that incident quantum of energy.

When a meteoroid enters the atmosphere, frictional, pressure, and chemical interactions with the atmospheric gasses cause the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting / falling star.

When thrown against a hard surface, the glass would shatter and the contents would instantly ignite, liberating choking fumes of phosphorus pentoxide and sulphur dioxide as well as producing a great deal of heat.

When necessary, we should make it clear that countries which choose to derive marginal advantages from the cold war or to exploit their potential for disrupting the security of the world will not only lose our sympathy but also risk their own prospects for orderly development.

When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely.

When calcium is leached from the needles of red spruce, these trees become less cold tolerant and exhibit winter injury and even death.

When El Niño conditions last for many months, extensive ocean warming and the reduction in Easterly Trade winds limits upwelling of cold nutrient-rich deep water and its economic impact to local fishing for an international market can be serious.

When fully chilled, the most common ratios of gelatin to liquid ( as instructed on commercial packaging ) usually result in a custard-like texture which can retain detailed shapes when cold but melts back to a viscous liquid when warm.

When the body is too cold, the arrector pili muscles found attached to hair follicles stand up, causing the hair in these follicles to do the same.

There he repeated in a different form all that he had already said, for all the world as if he had a gramophone fixed in his brain ... When I took leave, he subjected me to an interminable handshake, meanwhile fixing his cold blue eyes on mine, and repeating almost word for word what he said to me on arrival ... I felt I should never be able to establish any human contact with this man " In early June 1940, when Mussolini informed Hitler that he at long last would enter the war on 10 June 1940, Hitler was most dismissive, in private calling Mussolini a cowardly opportunist who broke the terms of the Pact of Steel in September 1939 when the going looked rough, and was only entering the war in June 1940 after it was clear that France was beaten and it appeared that Britain would soon make peace.

When Admiral Bokhari heard the news, a strong and powerful protest was launched against the Prime minister and the silent cold war with the admiral came to end with Prime minister approving the relieving papers of Admiral Bokhari the next morning.
