4.92892 but not exactly sure
84280/3011 or 27.9907g Fe
Explanation:
(3.01 * 10^23)/1 x 1 mol Fe/(6.022 * 10^23) x 56g Fe/ 1 mol Fe = 27.9907 g Fe
when the temperature of a fluid increases the kinetic energy of the molecules increases.
<u>Explanation:</u>
- when there is a change in liquid temperature then there will be changes in its properties especially in the (KE) kinetic energy of molecules and the density of the fluid.
- Due to the addition of the heat kinetic energy of the fluid molecules as it gains the heat, the intermolecular movement increases so there will be in the increased collision between the molecules which results in breaking the intermolecular force.
- Whenever the heat is applied to any matters nature is to tend to expand so the fluids also expand which results in the decrease in the density of the liquid.
- And also due to the increases in the kinetic energy, the speed of the fluid also increases.
