Everyday Science MCQs

Thermal radiation travels as electromagnetic waves.
It does not require a material medium.

Pressure inside the cooker increases above atmospheric pressure.
Water then boils at a higher temperature and cooks food faster.

Pitch rises as vibration frequency increases.
Low frequencies produce lower-pitched sounds.

Density compares mass with the space occupied.
It is calculated as mass divided by volume.

Space between the Sun and Earth is nearly a vacuum.
Solar energy reaches Earth as electromagnetic radiation.

Visible light is part of the electromagnetic spectrum.
It can travel through a vacuum.

Gravity continuously accelerates the ball downward.
After slowing to a stop, it begins falling.

Ice has an open crystal structure that occupies more volume.
Its lower density causes it to float on water.

Wood and many plastics conduct heat poorly.
They reduce heat transfer to the user's hand.

Non-luminous objects become visible when illuminated.
Reflected light enters the eyes and forms an image.

Friction resists sliding or rolling between surfaces.
It can produce heat and slow moving objects.

Freezing expands water into a less dense solid structure.
The resulting ice is buoyant in liquid water.
