The temperature inside and outside the glass window is maintained at | PGMN Solutions

The temperature inside and outside the glass window is maintained at 〖10〗^∘ C and -〖10〗^∘ C respertively. The heat conducted per minute through it is 200 calories. It is same if the outside temperature is now maintained at -〖17〗^∘ C. The temperature inside the window is (A) 276 K (B) 250 K [C) 246 K (D) 223 K ________________________________________________________________ 🚀 Step-by-Step Solution to Solve This Question 🚀 📌 Chapter: Thermal Properties of Matter 📌 Topic: Heat Conduction and Temperature Gradient 🔹 Step 1: Understand the core concept of steady-state heat conduction In a steady-state condition, the rate of heat conducted through a material remains constant if the thermal conductivity, area, and thickness of the material are unchanged. 🔹 Step 2: Use the idea of constant heat flow It is given that the heat conducted per minute remains the same, even when the outside temperature changes. Initially, the inside temperature is ten degrees Celsius and the outside is negative ten degrees Celsius. This gives a temperature difference of twenty degrees Celsius. 🔹 Step 3: Apply the concept to the second situation In the second situation, the outside temperature is negative seventeen degrees Celsius. Since the heat flow is the same as before, the new temperature difference must also be twenty degrees Celsius, to maintain the same heat flow. 🔹 Step 4: Find the new inside temperature If the outside is negative seventeen degrees Celsius and the temperature difference remains twenty degrees Celsius, the inside must be three degrees Celsius. Now convert this to Kelvin by adding two hundred seventy-three to the Celsius value. Three degrees Celsius plus two hundred seventy-three gives two hundred seventy-six Kelvin. ✅ Final Answer: (A) 276 K 🚀 🔥 Pro Tip: When heat flow remains constant, keep the temperature difference the same. Always remember to convert Celsius to Kelvin when final answers are asked in Kelvin. __________________________________________________________________________ 📽️ Must watch if you're preparing for MHT-CET 2025 Physics.
