A 25.0 g sample of mercury is cooled from 50 °C to 10 °C. If the specific heat of mercury is 0.14 J/g x °C, calculate the amount of heat energy lost in the process.

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
