Asample of gas in a balloon has an initial temperature of 37c and a volume of 1560 l. if the temperature changes to 82c , and there is no change of pressure or amount of gas, what is the new volume, v2, of the gas? in liters?
what celsius temperature, t2 , is required to change the volume of the gas sample in part a ( = 37 , = 1560 t1=37c, v1=1560l) to a volume of 3120 l? assume no change in pressure or the amount of gas in the balloon. in c?

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is called a
