Answer:
the si unit is joule or kelvin
Question - A student models the relationship between the pressure p of a gas and its temperature T as p = x + yT.
The units of p are pascal and the units of T are kelvin. What are the fundamental SI units of x and y?
Given - Relationship between pressure of gas and it's temperature p = x + yT.
Find - Fundamental SI units of X and y.
Solution - Finding SI unit of x-
As per given relationship, p is directly proportional to X. Thus, unit of X is Pascal which in SI unit kgm-¹s-².
Finding SI unit of y-
According to given relationship, p = yT.
So, y = p/T. Now, the units of y will be Pascal/Kelvin. Hence, SI unit of y will be kgm-¹s-²K-¹.
Therefore, option A is correct answer.
Pressure in simple words is defined as "force applied perpendicular to the surface of an object per unit area". Temperature in simple words is defined as "degree of heat present in an object".
