Answer:
A natural number greater than 1 that has only itself and 1 as factors is called a <u>prime</u> number
Step-by-step explanation:
- A prime number is a natural number greater than 1, that has only two factors;- the natural number itself and 1.
- Example:
- The factors of 13 are {1,13}, therefore 13 is a prime number.
- The factors of 2 are {1.2}, therefore 2 is also a prime number.
- Composite numbers have two or more factors.
- An exponential number is a power of natural numbers. An example is
- The first choice is correct

Answer:
i. When the temperature is above F, it changes to gas.
ii. When the temperature is below F, it changes to solid.
Step-by-step explanation:
Matter generally exists in either a solid, liquid or gaseous form. With each phase having a certain range of temperature.
Temperature scale of a given substance can be either in Celsius, Fahrenheit or Kelvin. And conversion from one scale to another can be achieved. Example, Celsius scale can be converted to Fahrenheit by:
F = θ + 32
where: F is the equivalent temperature in Fahrenheit, θ is the value of temperature in degree Celsius.
Given that: melting point of the substance = C
⇒ F = x
+ 32
= F
The boiling point = C
F = x
+ 32
= F
The melting point of the substance is F, and boiling point is
F.
Therefore, the range of temperatures for which the substance is not in a liquid state are:
i. When the temperature is above F, it changes to gas.
ii. When the temperature is below F, it changes to solid.
