What else can I help you with?
What term for reactions that require energy input?
Endothermic reactions require energy input to occur. The energy needed is absorbed from the surroundings, resulting in a decrease in temperature during the reaction.
WhAT reactions requires a net input of energy from its surroundings?
Endothermic reactions require a net input of energy from their surroundings to proceed. These reactions absorb heat from their surroundings, resulting in a decrease in temperature of the surroundings.
Which process in the human body does not require energy input from respiration?
Diffusion is a body process that does not require energy from respiration.
What doesn't require energy?
Processes such as gravity, diffusion, and osmosis do not require energy input to occur. Additionally, objects at rest do not require energy to maintain their state.
Process of vaporization require an input of energy?
Yes, the process of vaporization does require an input of energy. The energy is required to break the intermolecular forces of a given substance. The intermolecular forces is usually very strong.
Is there a generator out there that doesnt require any input energy?
no there must at least be an initial input to get it started.
What type of reaction releases energy and does not require initial energy to occur?
All reactions require an activation energy. Some appear not to because that energy is provided enough by their temperature. Thus, there is no reaction that does not require any initial energy to occur. A reaction that results in an overall release of energy is called an exothermic reaction.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
Does a cooker need energy?
Yes, all ovens/cookers require some energy (fuel) input in order to get them to heat up. For example electric hobs require an electrical imput, gas cookers require gas as their fuel (energy) etc... Even solar cookers have a solar energy input.
A student performs a reaction twice. in the second trial she raises the temperature by 20 degrees C and notices that the reaction takes place more quickly. is the reaction endothermic?
Yes, raising the temperature and causing the reaction to occur more quickly is indicative of an endothermic reaction. This is because endothermic reactions require energy input in the form of heat to proceed faster.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Does the same amount of energy increase the temperature of different sized particles by the same amount?
No, the same amount of energy does not increase the temperature of different sized particles by the same amount. This is because temperature change depends on the mass of the particles; larger particles require more energy to achieve the same temperature change as smaller particles. Therefore, the specific heat capacity and the energy distribution among particles also influence how temperature changes with the energy input.
