Answer:
Step-by-step explanation:
Given:
for x≤1400; N = 5
So, Δx = =∑C(a + nΔx).Δx
=C(0)Δx + C(280)Δx + C(560)Δx + C(840)Δx + C(1120)Δx
= Δx[C(0) + C(280) + C(560) + C(840) + C(1120)]
= 280[49 + 42.616 + 34.664 + 25.144 + 14.056]
=280[165.48]
=46334 approx
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.
