What happens to the particles when thermal energy is added or removed?
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
When you add heat energy what happens to the density?
When heat energy is added to a substance, its particles gain more kinetic energy and move more vigorously. This increased motion can cause the particles to spread out, which leads to an increase in volume and a decrease in density of the substance.
What is added to hinges of doors to lessen friction?
A lubricant such as WD-40 or silicone spray can be added to hinges to reduce friction and ensure smooth operation.
What is an example where friction is small between 2 objects?
An example where friction is small between two objects is when a sled is placed on ice. The smooth surface of the ice causes very little friction between the sled and the ice, allowing the sled to slide easily.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What would be an example of a helpful decrease in friction?
Deep tread added to snow tires.
When citric acid is added will the pH increase or decrease?
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
What is the impact of grinding aid triethanolamine?
Triethanolamine is added to metalworking fluids because: - it is a powerful surfactant - decrease the pH - as a protection substance against corrosion
Why do you have to mix oil and gas?
An engine needs lubrication to reduce friction and prevent overheating of the internal parts. Oil is added to the gasoline in a 2-cycle engine because this type of engine does not have an oil reservoir.
What happens to the particles when thermal energy is added or removed?
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
What do you call it when oxygen is added to a substance?
When Oxygen is added to a substance it is called oxidation.
When you add heat energy what happens to the density?
When heat energy is added to a substance, its particles gain more kinetic energy and move more vigorously. This increased motion can cause the particles to spread out, which leads to an increase in volume and a decrease in density of the substance.
What is the definition for reduction in chemistry?
Reduction in chemistry refers to a chemical reaction in which a substance gains electrons, either by accepting hydrogen atoms or by losing oxygen atoms. This process results in a decrease in the oxidation state of the substance.
What is added to hinges of doors to lessen friction?
A lubricant such as WD-40 or silicone spray can be added to hinges to reduce friction and ensure smooth operation.
What is the difference between a dilutant and a diluent in the context of pharmaceutical formulations?
A dilutant is a substance that is added to a drug to decrease its concentration, while a diluent is a substance that is added to a drug to increase its volume without affecting its concentration. In pharmaceutical formulations, dilutants are used to reduce the strength of a drug, while diluents are used to adjust the physical properties of the drug.
What happens to a substance's temperature as it god through the change of state?
During a change of state, the temperature of a substance remains constant. This is because the energy being added or removed is used to break or form intermolecular bonds rather than increase or decrease the substance's kinetic energy.
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
