Answer:

Mass, color, shape, volume, and density are some physical properties. The answers to the question about the present are physical properties. Density is an important physical property. Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies.

Matter is anything that has mass and takes up space. It can be in the form of solids, liquids, or gases. When you look at an object, you are able to see many of its properties. Scientists classify matter based on its chemical and physical properties that have been observed and tested. Some physical properties are only known through experimentation, while others are visible to the naked eye.

Explain temperature change and process of change on a cooling curve:
blsea [12.9K]

Answer:

When we heat a solid, the energy supplied is used to increase the kinetic energy of its molecules, and thereby its temperature increases. ... From solid to liquid at melting point or from liquid to gas at boiling point) is termed as its latent heat.

Process:

A cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. This is because the matter has more internal energy as a liquid or gas than in the state that it is cooling to.  

The initial point of the graph is the starting temperature of the matter, here noted as the "pouring temperature". When the phase change occurs there is a "thermal arrest", that is the temperature stays constant. This is because the matter has more internal energy as a liquid or gas than in the state that it is cooling to. The amount of energy required for a phase change is known as latent heat. The "cooling rate" is the slope of the cooling curve at any point.

12345 [234]

Answer:

A. 5 m/s

Explanation:

From the graph, for the first 2 seconds, the graph is a straight line meaning that the slope is a constant.

Average speed of an object is the rate of change of position. Here, the position of the object changes from 0 m to 10 m for a time interval of 2 seconds.

The change in position (\Delta x) and time interval (\Delta t) are given as:

\Delta x=10-0=10\ m\\\Delta t=2-0=2\ s

Therefore, the average speed (s_{avg}) is given as the ratio of the total change in position and the time interval for the change.

s_{avg}=\frac{\Delta x}{\Delta t}=\frac{10-0}{2-0}=\frac{10}{2}=5\ m/s

Hence, the average speed is 5 m/s.
