Why is it important to stop heating when the temperature starts increasing?
Now I'm no scientist but my guess is to prevent overheating
What is difference between a mechanical stopwatch and an electronic stopwatch?
A mechanical stopwatch can measure a time interval of up to 0.1 seconds. It has a knob that is used to wind the spring that powers the watch. It can also be used as a start-stop and reset button. The watch starts when the knob is pressed once. The Electronic Stopwatch keeps time for an unlimited number of splits and registers 1/100th for the first 30 seconds, and 1 second . thereafter for up to 24 hours. It includes a programmable alarm, and displays the current date, time and month.
Do scientist study radiation?
Yes, they do. I know for a fact, because in 'The Answers Book 1', it says that they study something that starts with 'u' having a gas inside it and eventually turning into lead. It's a kind of radioactive rock, I think. Plus, isn't that kind of stuff the kind of stuff that scientists study?

The half-life of Au-198 is 2.7 days When there are 800 atoms of Au-198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8.1 days how many atoms of Au-198 remaining?
8.1 days is, if half-life is 2.7 days, 3 half-lives. 12.5%, or 12.5 g, of 79198Au would remain after three half-lives.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What is the greatest length of time measured on a stopwatch?
There is no upper limit; when the stopwatch reaches the largest number of seconds it can count, it simply starts over. It is your job to count the number of times it starts over. Most digital stopwatches can time up to 20 hours, resetting after 19:59:59.99.
