When a layer of air with temperatures above freezing sits above a layer of subfreezing air near the ground, which type of precipitation is likely to form?
a. rain
b. snow
c. sleet
d. hail

The correct answer is option c, that is, sleet.

Explanation:

Generally, globular transparent ice pellets, which exhibit diameters of 0.2 inches or less, and which get produced as an outcome of the freezing of raindrops or the freezing of the majorly of melted snowflakes is known as sleet.  

The formation of sleet may take place when a warm layer of air is situated above a below-freezing layer of air at the surface of the Earth. In certain parts of the United States and in Great Britain, an amalgamation of snow and rain is known as sleet.  

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
