Explanation

There are 3 main states of matter:

• Solid (fixed shape and volume)
• Liquid (fixed volume, but takes shape of container)
• Gas (neither fixed shape nor fixed volume)

Explanation

The world's most consumed drink, after water, is made from the Camellia sinensis plant.

It is used to produce tea.

Explanation

An image formed by a convex lens is called real and inverted.

This occurs when the image is formed on the opposite side of the lens from the object.

This is upside down relative to the object.

Explanation

• When light is focused in front of the retina, it creates a blurred image, indicating nearsightedness (myopia).
• This occurs because the eyeball is too long or the cornea is too steep.
• It causing light to focus before reaching the retina.

Explanation

• Measuring cylinders are designed to measure the volume of liquids.
• It allowing for precise measurements in scientific experiments and procedures.

Explanation

• A constellation is a group of stars that, when viewed from Earth, form a pattern or shape that is recognizable.
• It has been given a specific name, such as Orion, Cassiopeia, or Ursa Major.

Explanation

• The hottest stars are the blue stars, and their temperature is around 25,000°C.
• These stars emit blue light due to their extremely high surface temperatures, which can range from 20,000 to over 30,000 degrees Celsius.

Explanation

• The color of an opaque or non-luminous object is the color of light it reflects.
• When light hits the object, some wavelengths are absorbed, and the remaining wavelengths are reflected, which is what we perceive as the object's color.

Explanation

• The triangular prism is one of the most commonly used dispersive prisms, particularly in spectroscopy and optical instruments.
• It is called a dispersive prism because it separates light into its different colors (spectrum) due to the different refractive indices of the glass for different wavelengths.

Explanation

• A Concave Mirror has a curved reflecting surface that bulges inward, like the front side of a spoon.
• This type of mirror is used in telescopes, solar concentrators, and other applications where light needs to be focused.
