Explanation:
Answer:
All change in their form in relation to amount of heat energy.
Explanation:
- Due to the chemicals bonds that are within these forms of matter. The solids are compact and have strong bonds where the atomic molecules are attached to each other firmly.
- While in gases the bonds are least developed and molecules are able to move freely with the least friction. In water, the bonding is neither compact nor loose.
- All this is possible due to the addition of heat to molecules as they gain energy they start to move. Hence changes their forms, while the water molecules one hydrogen bond that is attached to nonbonding pairs of electrons. The water molecules form and reform continuously.
Answer:
Curves around objects
Explanation:
Diffraction is a property of light described by bending of light around an object. This ability of light to bend around edges has facilitated optical effects of light where there is interference of light waves. Other properties of light are: reflection, refraction, polarization, scattering of light, and interference of light.
Answer: 68852 millijoules = 16.46 calories
Explanation:
Given;
Convert 68852 millijoules to calories.
1 calorie = 4.184J = 4184millijoules
Therefore,
1 millijoule = 1/4184 calories
68852 millijoule = 68852 × 1/4184 calories
= 16.46 calories
