Answer:
B
Explanation:
When the temperature of the substance increases, the velocity increases which makes the movement of the particles to speed up. This causes the particles to increase. Therefore, as the temperature increases, the kinetic energy of the particles also increases.
Answer:
C. Chemical reactions may have deteriorated the rubber
Explanation:
A tire ages with time and most of the time this happens due to chemical reactions in the rubber parts. This could happen faster due to heat and sun.
As a tire is deteriorating or aging, a chemical change happens. What happens is that more chemical bonds are going to be produced with time between the molecules. We call this the process of oxidation. This actually bad for the tire, because the rubber would turn out to be stuffs d strong causing the tires thread to separate and also disintegration would occur.
B) is a right answer because molar mass equal molecular atomic mass meaning Ar(Na)=23 and so M(Na)=23 as well.
Answer:yes they have the same mass.
2,000 times as massive as an electron.
The nucleus
electrons make the greatest contribution to the chemical properties of the atom.
Explanation:
Answer:
The coldest temperature possible
Explanation:
Absolute zero = 0 K
A. is wrong. 0 °C = 273 K
B. is wrong. -210 °C = 63 K
C. is wrong. 32 °F = 273 K
E. is wrong. -196°C = 77 K
