Answer:
Explanation:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Answer: it involves a change in physical properties, such as melting, condensing, evaporating, change of color, shape, size, volume an density
A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image.
Astronomers use a telescope to observe distant things. Curved mirrors are used by the majority of telescopes, including all large telescopes, to collect and concentrate light from the night sky.
Refracting telescopes have been used for centuries and are still commonly used today, especially for viewing bright objects such as the Moon and planets.
However, they have some limitations compared to other types of telescopes, such as difficulty in making large lenses without distortion and the tendency to produce chromatic aberration, which can cause images to appear blurred or discolored.
Despite these limitations, refracting telescopes remain popular among amateur astronomers and are still used in many scientific applications.

Answer:
both are true
Explanation:
thunder: when air molecules are heated, they expand. Sound waves move faster in warm air than they do in cool air. and The speed of light as it travels through air is much faster than that of sound.
well if this helps you I do not know what "h and n" is but I do know that
friction produces heat
