G1 Physics · Accepted Answer

Apply energy conservation. Sensible heat is Q=mcΔT and phase-change heat is Q=mL. Heat lost by hotter parts equals heat gained by colder parts. Evaluating the given data/statements gives 25. Therefore the correct answer is B.

A thermometer graduated according to a linear scale reads a value x o x_{o} x o ​ when in contact with boiling water, and x o x_{o} x o ​ /3 when in contact with ice. What is the temperature of an object in °C, if this thermometer in the contact with the object reads x o x_{o} x o ​ /2 ?

A thermometer graduated according to a linear scale reads a value x o x_{o} x o when in contact with boiling water, and x o x_{o} x o /3 when in contact with ice. What is the temperature of an object in °C, if this thermometer in the contact with the object reads x o x_{o} x o /2 ?
