Answer:

97200yrs,

Explanation:

Given parameters:

Half-life of Plutonium - 239  = 24300yrs

Mass of the isotope  = 8kg

Unknown:

Number of years it will take for the amount to reduce to 1kg = ?

Solution:

The half -life of any substance is the time taken for half of the compound to decay to half its original composition.

             <em>  Start     first half life     second half life   third half life</em>

mass       8kg              4kg                   2kg                    1kg

Time         0yrs            24300            48600               97200

By 97200yrs, the mass would have been 1kg

A sample of gas occupies a volume of 67.5 mL . As it expands, it does 131.0 J of work on its surroundings at a constant pressure
baherus [9]

Answer:

The final volume V2=1.3175L

Explanation:

between work ( w), pressure ( P ) and volume ( V ) is the following:

w=−PΔV

where,

ΔV=V2−V1

It was stated that the gas is expanding, then the work is done by the system and it is of a negative value .

Note that work, should be expressed in 1L⋅atm=101.3J
