Question

A reaction occurs when solid X is placed into solution Y. As a result, the temperature of the new solution increases by 3°C. The temperature rises another 2°C when more of solid X is added to the solution. What does this indicate about the effect of adding more solid?

Answer 1

The right answer is a.it increased the number of molecular collisions.

Thermodynamic temperature is a formalization of the experimental notion of temperature and is one of the main magnitudes of thermodynamics. It is intrinsically linked to entropy.

Usually denoted T, the thermodynamic temperature is measured in kelvins (symbol: K). Often referred to as "absolute temperature", it is an absolute measure because it directly reflects the fundamental physical phenomenon that underlies it: the agitation of the particles constituting matter (translation, vibration, rotation, electronic energy levels ) there is a directly proportional relationship between the number of molecules present in a solution, the number of collisions (increased by the number of molecules), and the temperature (increased by the number of collisions).
