6. A piece of solid gold was heated from 274K to 314K. 35.73 of energy was needed to raise the temperature.
ivanzaharov [21]

From Q = mcΔT, we can rearrange the equation to solve for mass, m = Q/cΔT. The specific heat capacity, c, of solid gold is 0.129 J/g °C. I'm assuming that the energy is given in joules, as it's not specified in the question as written.

m = Q/cΔT = (35.73 J)/(0.129 J/g °C)(40.85 °C - 0.85°C)

m = 6.92 g of gold was present

What is the main "impurity" collected with the oil?
NikAS [45]

Answer:

Sulfur is considered an “impurity” in petroleum. Sulfur in crude oil can corrode metal in the refining process and contribute to air pollution. Petroleum with more than 0.5% sulfur is called “sour,” while petroleum with less than 0.5% sulfur is “sweet.”

The characteristics of two methods of heat transfer are listed below: Method A: No material medium is required and heat is trans
Mumz [18]

<em>Answer:</em>

  • Method A is radiation and Method B is convection.

<em>Explanation:</em>

Radiation:

  • The radiations are basically electromagnetic radiation that does not required any medium to travel. They can travel not through  air and solid material but can travel through  vacuum.

Convection:

  • The convection is method of transfer of heat through liquid or gaseous medium.

<em>Summary:</em>

  • As in method one, there is no medium, so radiation can pass without medium
  • As in method two, there is liquid or gases medium, so heat travel through this medium will be convection.
