If the samples are on the same planet and touching, then the hot one cools off and the cold one warms up. Energy flows from the hot one to the cold one until their temperatures become equal somewhere in the middle.
Answer: How does the temperature of the samples change?
As the temperature increases, the rate of reaction increases. Particles can only react when they collide. ... Increasing the temperature increases reaction rates because of the large increase in the number of high energy collisions. It is only these collisions that will produce the reaction. Low-temperature experiments prevent denaturation of samples. ... When the temperature of the protein water solution is reduced below the ... The FB peak position does not change but its intensity changes proportionally with variation of intensity of incident radiation.
Which way does the energy flow?
Energy flow in ecosystem occurs by food chain from producer to consumers. ... Then energy is transfered from producers to consumers, called as heterotrophs. Primary consumers are called as herbivores. Herbivores are eaten up by secondary consumers, called as carnivores. Energy flow is always unidirectional. Energy flows progressively from one trophic level to another and cannot revert back. In most of the natural ecosystems, energy comes from the sun, it is trapped by producers and then pass on to successive trophic levels in the form of food.
The value of acceleration due to gravity is greater in terai than in mountain. In terai region the radius of earth is less as it lies close to the centre of the earth. Thus, the value of g is more in terai region.
