Sound waves travel faster through <em>solids</em> than they do through gases or liquids. <em>(C) </em>They don't travel through vacuum at all.
Example:
Speed of sound in normal air . . . around 340 m/s
Speed of sound in water . . . around 1,480 m/s
Speed of sound in iron . . . around 5,120 m/s
Answer:

balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
Answer: Maryam is driving her car when she glances at the temperature displayed on her dashboard. It says that the temperature is currently 78 degrees outside. This temperature is called a Sensation.
Explanation: To find the answer, we need to know more about the Sensation, perception and psychophysics.
<h3>What is sensation, perception and psychophysics?</h3>
- Sensation can be defined as the process by which the physical energy from objects in the world stimulates the sense organs.
- The process in which the brain interprets and organizes this sense of information is called, Perception.
- The branch of physics that deals with the study of how physical properties of stimuli connected with the people's experience of stimuli is called the Psychophysics.
Thus, we can conclude that, the process of sensation happens here.

Answer:
The lid becomes tighter
It becomes tighter because metals have a lower heat capacity than glass meaning their temperature drops (or increases) much faster than glass for the same energy change. So in this example, the metal will contract faster than the glass causing it to be more tighter around the glass.
