Answer:
10 °C
Explanation:
Applying
q = cm(t₂-t₁)............... Equation 2
Where q = heat energy, c = specific heat of ethanol, m = mass of ethanol, t₁ = initial temperature, t₂ = Final temperature.
Given: c = 2.44 J/g.°C, m = 300 g, q = 14640 J, t₂ = 30°C
Substitute into equation 2 and solve for t₁
14640 = 2.44×300(30-t₁)
14640 = 732(30-t₁)
732(30-t₁) = 14640
(30-t₁) = 14640/732
(30-t₁) = 20
t₁ = 30-20
t₁ = 10 °C
Conductors, type SIS, for switchboard wiring, have a maximum operating temperature of: 194 degree Fahrenheit.
<u>Explanation:</u>
A Panelboard or Switchboard wire is known as SIS.This type of SIS, have tin coating and it is manufactured with a copper conductor insulation. It is helpful for facilitating solder and also it will be easy to fix them in tighter spaces because for their flexible nature.
As they are insulated with XLPE they can be used at a voltage operating at 600 V and can be used at a temperature of 194 degree Fahrenheit or 90 degree Celsius. of The XLPE(Cross-Linked Polyethylene) insulation is rated for use at 90°C in either wet or dry locations at an operating voltage of 600 V. They can be used for distribution, panel and switch board wiring.
Answer:
In general solids are easier to transport than liquids, but the above metal example is a valid one and the only other one that comes to mind is that of concrete. It is mixed as a liquid and transported as such, but then sprayed or laid down to dry and form a solid surface or filler.
