In chemistry, increasing the concentration of one of the reactants increases the reaction rate because there are more reactant particles available for successful collisions and subsequent reactions.
In the field of chemistry, the concentration of reactants can significantly impact the rate of a reaction. According to the rate law, the rate of a reaction is directly proportional to the concentration of the reactants. Therefore, if you increase the concentration of one of the reactants, the reaction rate will also increase. This is because there are more particles available to collide and react, which increases the likelihood of successful collisions, thereby accelerating the reaction rate. For example, if you have a cup of tea and you increase the concentration of sugar (one of the reactants), the sugar will dissolve faster, indicating a faster reaction rate.

b. energy cannot be converted into other forms of energy
c. potential energy can be converted into kinetic energy, but not vice virsa
d. kinetic energy can be converted into potential energy, but not vise virsa
Moving water can be used to produce electricity because most forms of energy can be converted into other forms. The kinetic energy of water is used to generate electrical energy.
According to the law of conservation of energy, energy can neither be created nor be destroyed. However, one form of energy can be transformed to the other form.
The generation of electrical energy is a good example of energy transformation. Electrical energy is generated from the thermal energy, hydroelectric energy or nuclear energy.
Moving water have enough kinetic energy to provide mechanical energy for a generator that convert this energy into electrical energy. Therefore, option a correctly describe the possibility of energy transformation.

Answer:
Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.
If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.
If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.
Answer is: heat conductivity.
Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
