What three processes occur in every heat engine?
1. a high temperature source is used to remove thermal energy from 2. a low temperature receptacle is where the thermal energy can be received 3. thermal energy is converted to work I'm only a high school Advanced Physics student, but I'm almost certain this is right.
Does physical change occur when energy is added or removed?
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
What is a isolated system?
An isolated system is a system in which neither matter nor energy can enter or leave the system. This means that no interactions with the surroundings can occur in terms of energy or matter exchange. The total energy and mass within an isolated system remain constant.
How does the transfer of kinetic energy to heat occur in a system?
When kinetic energy is transferred to heat in a system, it happens through the collision and movement of particles within the system. As the particles move and collide, their kinetic energy is converted into heat energy, increasing the overall temperature of the system.
When does thermal energy increase?
Thermal energy increases when the temperature of a system rises, causing the kinetic energy of its particles to also increase. This can occur through the addition of heat or energy input to the system.
What does it mean to be safe?
When you are safeguarded from something, you are immune or resistant to its negative effects. For example, "I have safeguarded the system from viral attack" means "I have added measures to prevent negative effects that may occur from viral attack".

Why do substance s expand when energy is added to them as heat?
When heat is added to a system, it increases the kinetic energy of the molecules. Increased K.E in system causes molecules to move further away from each other. This causes system to increase in volume. Significant increase in volume might not occur but at microscopic level it definitely changes.
Why does beating occur in a spring-mass system when a driving force is added?
because laplace transformations occur
Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.

Why do adiabatic temperature changes occur?
In adiabatic process heat is neither added nor removed from the system. So the work done by the system (expansion) in adiabatic process will result in decrease of internal energy of that system (From I st law). As internal energy is directly proportional to the change in temperature there will be temperature drop in an adiabatic process.

Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
When does thermal energy increase?
Thermal energy increases when the temperature of a system rises, causing the kinetic energy of its particles to also increase. This can occur through the addition of heat or energy input to the system.
