АСTIVITY 2
Direction: solve and analyze each of the following problem in neat and orderly manner.
1. A thermometer reading 180C is brought into a room where the temperature is 700C ; 1 minute later the thermometer reading is 310C. Determine the
thermometer reading 5 minutes after its brought into the room.
2. It takes 12 minutes for an object at 1000C to cool to 800C in a room at 500C. How much longer will it take for its temperature to decrease to 700C.
3. A thermometer reading 100C is brought into a room where the temperature is 180C ; 1 minute later the thermometer reading is 140C. how long does it take until
the reading becomes 160C.
4. A metal is heated up to a temperature of 5000C. it is then expose to a temperature of 380C. after 2 minutes the temperature of the metal becomes 1900C. when
will the temperature be 1000C? what is the temperature after 4 minutes?
5. A temperature is taken from an inside room to the outside, where the air temperature is 5 oF. After 1 minute, the thermometer reads 550F and after 5 minutes it
reads 300F. what was the initial temperature of the thermometer when inside the room?
