Zirconium tungstate is an unusual material because its volume shrinks with an increase in temperature for the temperature range 0.3 k to 1050 k (where it decomposes). in fact, the volumetric coefficient of thermal expansion is –26.4 × 10–6/k. determine the ratio δv/v0 for the above mentioned temperature range. express your answer in percent.
just watched a program with stephen hawking about time-travel and it turns out that the further you get away from gravitation, the faster time goes. in his experiment there were 20 nanoseconds in difference on 2 atomic clocks after 24 hours with 1 clock on top of a 3800 meter high mountain and 1 on the ground. so if you spend a lot of your time in a plane, you might live shorter because time is faster up there. pretty interesting, huh?
the answer is precipitate
the chemical reaction of cavendish involving zinc would be a reaction between hydrochloric acid and zinc yielding zinc chloride and hydrogen gas.
the work required to raise an object to a height is equal to the gravitational potential energy the object gains. (c)
