1) Reaction is exothermic because energy of products is less than energy of reactants
2) Energy is released because the reaction is exothermic
3) 350
4) 150
5) 500-350=150
6) 350-150=200
Answer:
Below 0° degrees Celcius
Explanation:
For deposition (gas to solid) to happen, the temperature has to be below 0° Celsius. If so, deposition occurs, and ice crystals form.
By conduction from your hand to the glass. By convection from your hand to the glass. By convection from the ice to your hand . By radiation from the ice to your hand.
Wind results due to difference in air pressure of air masses. Due to difference in pressure of two air masses, low pressure zone is created by lifting of one the air mass above the other as the movement of air takes place from higher pressure area to lower pressure area. This causes different wind speed in different areas. The direction of wind depends on its origin for example, a northerly wind always moves from north to south direction.
The scientist that came up with the idea of natural selection was Charles Darwin.
