If a cube of a certain metal increases its volume from 15 cm3 to 17 cm3 as the temperature increases from 12°C to 28°C, what is the metal's linear expansion coefficient?
Homework Answers
linear expansion coef = change in volume/ 3 * temp change * volume
= (17 - 15) / ( 3 * 28-12 * 15
= 2.78 * 10^-3
Del V= 2 cm3
Vo=15
del T= 28-12= 16
coefficient= Del V / Vo * del T
= 2/15 * 16
= 0.0083333

To treat a burn on your hand, you decide to place an ice cube on the burned skin. The mass of the ice cube is 10.1 g, and its initial temperature is-13.1 °C. The water resulting from the melted ice reaches the temperature of your skin, 31.7 °C. How much heat is absorbed by the ice cube and resulting water? Assume that all the water remains in your hand. Constants may be found in this table. You heat a 503...

A glass flask whose volume is 1000 cm3 at a temperature of 0 ∘C is completely filled with mercury at the same temperature. When the flask and mercury are warmed together to a temperature of 52.0 ∘C , a volume of 8.10 cm3 of mercury overflows the flask. If the coefficient of volume expansion of mercury is βHg = 1.80×10−4 /K , compute βglass, the coefficient of volume expansion of the glass.
