So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...
Heat- Given off from thermal energy.
Thermal energy- what is given off when energy is lost.
Law of Conservation of Energy- Energy can neither be created or destroyed, it can only be transformed from one form to another.

The zero error in vernier caliper is read by the distance by which the zero of the movable part of the scale is shifted from the zero of the cm ruler in the tool, which is the unmovable part of the tool. The movable part has a scale accuracy of 0.1 cm, while the other has a scale accuracy of 1 cm. And we always use the lowest scale, which is here the 0.1 scale which has greater accuracy with 10 times the 1 cm ruler, to find our errors.
Hope this helps!

Answer:The material must absorb the light
Explanation:
The material needs to absorb the light and the energy in. There also needs to be refraction, or a change in the direction the light is going.

How far was the spring stretched at the moment it was released?
Answers
To find the force on the block, use Newton #1: F = m A
Force = (2.3 kg) x (0.27 m/s²)
Force = (2.3 x 0.27) kg-m/s²
Force = 0.621 Newton
The spring stretches 1 meter when to pull with 18 N of force.
To pull with only 0.621 N of force, it only has to stretch (0.621/18) of a meter. That's 0.0345 meter, or 3.45 cm .
Flammability
Reaction with bases
Solubility
Reaction with oxygen
Answers
Answer:
The correct answer is C) Solubility
Explanation:
Final answer:
Solubility is the example of a physical property from the given options, as it can be observed and measured without changing the substance's chemical identity.
Explanation:
The question is asking which of the listed options is an example of a physical property. A physical property is a characteristic of matter that can be observed or measured without changing the substance's chemical identity. Among the choices given - flammability, reaction with bases, solubility, and reaction with oxygen - solubility is a physical property. This is because solubility refers to a substance's ability to dissolve in a solvent, which can be observed without causing a chemical reaction. On the other hand, flammability and reaction with bases or oxygen are chemical properties, as they describe a substance's ability to react and form new substances.
