The unit conversion between rankine and kelvin is (linear, exponential, quadratic, none of the above)?
the unit conversion between degrees celsius and degrees fahrenheit is (linear, exponential, quadratic, none of the above)?

Unit conversion between Rankine and Kelvin is linear.

Unit conversion between degree Celsius and degree Fahrenheit is linear.

Explanation:

Relation between rankine and Kelvin is

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value .

Relation between degrees Celsius and degrees Fahrenheit is given by

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope and negative intercept of .

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
