The process of adding hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products is calle
Viktor [21]

Hydrogenation is a process that involves adding hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.

<h3>What is hydrogenation?</h3>

Hydrogenation can be defined as a chemical process that involves an addition of hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.

<h3>The purpose of hydrogenation.</h3>

In Science, some of the purpose of hydrogenation include the following:

  • Conversion of liquid oil into solid fat.
  • To alter a fat's consistency level.
  • To stabilize a fat or an oil.

1(30%). A thin plate black body, insulated at the bottom is placed faced up in a room with wall temperatures of 30 C. Air at 0 C
ch4aika [34]

Explanation:

The given data is as follows.

         Heat transfer coefficient (h) = 12W/m^{2}.C

         Plate temperature (T_{1}) = 30 ^{o}C = 303 K

         Steady state temperature (T_{2}) = ?

Hence, formula applied for steady state is as follows.

       (h \times A \times \Delta T)_{air} = \sigma \times A \times (T^{4}_{1} - T^{4}_{2})_{plate}

Putting the given values into the above formula as follows.

       (h \times A \times \Delta T)_{air} = \sigma \times A \times (T^{4}_{1} - T^{4}_{2})_{plate}

        12 \times (T_{2} - 273) = 5.67 \times 10^{-8} \times [(30 + 273)^{4} - T^{4}_{2}]

                  T_{2} = 282.66 K

                              = (282.66 -273)^{o}C      

                              = 9.66 ^{o}C      

Thus, we can conclude that the steady state temperature will be 9.66 ^{o}C.

What causes gas particles to collide with the walls of their containers?
blondinia [14]

Answer:

Kinetic energy

Explanation:

The kinetic energy of a particle is directly proportional to the temperature of it. An increase in temperature increases the speed in which the molecules move, causing t[he particles to collide with the walls of their containers.
