Answer:
The reaction will absorb energy
Explanation:
A potential energy diagram shows the energy changes that occur during a chemical reaction. It is also called a reaction progress curve. The diagram shows the changes that occur as reactants are converted into products.
The best conclusion according to the energy diagram of the chemical reaction is that the reaction will absorb energy.
Answer:
B. The water must gain thermal energy from its surroundings.
Explanation:
Boiling is the process whereby a substance is changed from a liquid state to a gaseous state due to the application of heat. For boiling to be achieved, a liquid substance must reach or exceed its boiling point, which is the specific temperature at which a specific liquid boils.
For this change of state i.e. from liquid to gas, to occur, atoms or molecules of the liquid must gain kinetic energy and move faster. However, this kinetic energy cannot be attained without a rise in temperature, which causes the molecules to gain THERMAL ENERGY or heat energy and move fast. Thermal energy is the energy that arises from a hot substance.
Therefore, for water to boil at a given pressure, it must gain thermal energy from its external surroundings, which causes its molecules to have an increased kinetic energy and move faster. This fast movement of the molecules causes the transition of phases (from liquid to gas).
Answer:
the wheels and force of your foot pushing off of the ground.
Answer : Option B) Energy from the environment fuels production.
Explanation : Environmental fuels can be produced from lands and contribute towards production. The land can contribute for the production of a Biogas plant and help in generating energy from the plant. It uses mainly decaying matter and household wastes which are decomposed and then produce methane gas is then connected to the household kitchens.
