The volume v (measured in cubic metres) of a certain amount of gas is determined by the temperature t (measured in kelvin) and the pressure p (measured in megapascals) by the formula v = 0.08 t p . calculate the values of ∂v ∂p and ∂v ∂t when p = 0.2 mpa and t= 340 k. (give exact answers.) then determine the units for each partial derivative.

Which of the following represents a virtual image?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
