- A thermometer reading is 60oF at 3:00 AM and a Civil Engineering student takes it outside where the air temperature is 20oF. At 3:10, the reading is 30oF. At 3:15, the thermometer is taken back indoor where the thermometer is 60oF. What is the thermometer reading at 3:20AM. a. What is the value of the constant of proportionality? b. The temperature of the thermometer at any time t is given by ____________?A thermometer reading 18°F is brought into a room where the temperature is 70°F. One minute later the thermometer reading is 31°F. Determine the: a) temperature reading as a function of time b) temperature reading 5 minutes after the thermometer is first brought into the room.Two thermometer. one reading and the other are both immersed in a fluid. If the farenheit reading is half of the celcius reading, a.) What is the farenheit reading? b.)what is the equivalent temperature of the fluid in degrees rankine?

After ½ minute, the thermometer reads 110° F and it reads 145°F after 1 minute. What is the temperature in the oven?3. According to Newton's Law of cooling', the rate at which the heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium (when the temperatutre difference is very small). If a thermometer is taken outdoor, where the temperature is 6°C, from a room which temperature is 25C, and the reading drops 15°C in one minute, how long after its removal from the room will the reading be 8°C? after 45 secs what is the thermometer reading?An engineer carried an aneroid barometer from the ground floor to his office atop the Shangri La hotel in Mandaluyong City.
