Question
I REQUIRE ANSWER TO MY QUESTION ON FURNACE OIL--THE WEIGHT,VOLUME AND DENSITY RELATIONSHIP
IS IT TRUE THAT WEIGHT OF FURNACE OIL IN KILOGRAMMES REMAINS THE SAME WHEREAS VOLUME IN LITRES VARIES WITH VARIATION IN TEMPERATURE OF OIL? IF YES HOW TO ARRIVE AT CORRECT VOLUME WITH THE GIVEN WEIGHT?
Answer
This holds true for almost any substance:
Kilograms actually measures the mass of an object. Think of the mass of an object as the amount of stuff in the object. Mass is constant no matter where you are.
Weight, on the other hand, can change. If you go to the top of a tall mountain, you will weigh more than if you were on a boat in the ocean.
Volume is a measure of the amount of space a substance takes up. Generally, if you heat a substance up, it takes up more volume and if you cool it down it takes up less volume.
Density is a ratio of the amount of mass per a uint of volume like grams/liter.
