Experiments were done on a certain pure substance X to determine some of its properties. There's a description of each experiment in the table below. In each case, decide whether the property measured was a chemical or physical property of X, if you can. If you don't have enough information to decide, choose can't decide in the third column. physical or chemical? property experiment O physical A sample of X is carefully weighed and put inside a sealed calorimeter. The calorimeter is heated electrically, and the amount of heat added determined by monitoring the electrical current used. The temperature of X is carefully measured, and from the temperature change and the amount of heat added the value of H may be calculated. O chemical O (can't decide)

physical A small sample of X is put on the pan of a sensitive balance and its weight measured. Next, a magnet is brought near the pan, and the weight is measured again. From the difference of weights in and out of the magnetic field, the value of M may be calculated. M chemical O (can't decide) O physical A sample of solid X is carefully weighed and put inside a sealed flask. Pure hydrogen gas is added to the flask, and the mixture heated until the hydrogen starts being consumed. After hydrogen stops being consumed, the contents of the flask are removed and weighed, and from the increase in weight the value of may be calculated. Q O chemical O (can't decide)
