Answer:
b melting
Explanation:
The phase change the substance is undergoing is from solid to liquid and this is called melting.
- To understand this process, we need to know the the substance changing.
- A substance that contains particles that are not easily compressed and packed is a solid.
- Solids have fixed shapes and volumes.
- Liquids can easily flow although they cannot also be easily compressed.
The phase change from solid to liquid is facilitated by a melting process.

The answer to the problem is 7/10
Answer:
True
Explanation:
The accuracy level is usually determined by the difference between the experimental and correct value. It is important to note that the smaller the difference between the average experimental value and the correct (true) value, the more accurate it is.
When the difference is large then it means the accuracy level is low and not up to the required standard.
Kepler stated three laws of planetary motion.
First law states that the pathway of a planet is an ellipse with the Sun at one of the foci.
Second law states that an imaginary line joining the Sun and a planet sweeps out equal areas during equal lengths of time.
Third law states that the square of the period of the orbit of a planet is directly proportional to the cube of the length of the distance from the Sun.
Therefore, the answer is that Kepler's second law of planetary motion states that planets cover the same area during equal time periods.
