The relationship between Fahrenheit and Celsius is:
°F = 1.8*°C + 32
If we differentiate the given expression to find the relationship between a unit change of °F and °C, we get:
Δ°F = 1.8*Δ°C
This means that a change in 1 degree Fahrenheit is equivalent to a change of 1.8 degrees Celsius. Moreover, a one degree change in Fahrenheit is the same as a one-degree change on the Rankine scale, so, ranking the scales in order from higher change to lower change:
1) Fahrenheit = Rankine
2) Celsius = Kelvin

Answer:
26.2g = Mass of water in the calorimeter
Explanation:
The heat absorbed for the water is equal to the heat released for the metal. Based on the equation:
Q = m*C*ΔT
<em>Where Q is heat, m is the mass of the sample, C is specific heat of the material and ΔT is change in temperature</em>
<em />
Replacing we can write:
13.9g * 0.449J/g°C * (54.2°C-15.6°C) = m(H₂O) * 4.184J/g°C * (15.6°C-13.4°C)
240.9J = m(H₂O) * 9.2J/g
<h3>26.2g = Mass of water in the calorimeter</h3>
Answer:
Have some attraction towards each other
Explanation:
Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.
Hope this helps :-)

Answer:
CaF2
Explanation:
Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from hydronium, which is transformed into a water. Picture is attached.
