Question

what is Dimension?

what happens when we heat solid?​

Answer 1

Answer:

In physics and mathematics, the dimension of a mathematical space is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.

Answer 2

• Dimension is a measurement of length in one direction. Examples: width, depth and height are dimensions

• When a solid is heated, the molecules that make up the solid begin to vibrate. This causes them to take up more space, and the solid matter expands.
• If the heat continues to build, it may provide enough energy for the particles to break free from their strong attraction to one another, causing the solid to melt
