Consider a gray and opaque surface at 0°c in an environment at 25°C. The surface has an emissivity of 0.8. if the radiation in
valina [46]

The radiosity of this surface is 299.95W/m².

<h3>Calculation :</h3>

Given, € 0.8

Ta=0°C 273K

For opaque body., T = 0

a+ p = 1

€ = a (Kirchoff's Law)

p = (1-E)

Radiosity = leaving energy from the surface

= px 240 +€σT4

= (1-E) × 240 +0.8 x 5.67 x 10-8 (2734)

= (1-0.8) × 240 +0.8 x 5.67 × 10-8 (2734)

= 299.95W/m²

So, now after doing the calculations we can say that the radiosity of the surface was 299.95W/m².

The decomposition reaction of CO2(g) to produce carbon and oxygen gas consumes 462 kJ of energy. The energy levels of the produc
Semenov [28]

Answer:

higher, left

Explanation:

Given that the reaction consumes 462 kJ of energy. It means that the reaction is a endothermic reaction.

In the energy profile of the endothermic diagrams, The reactants are at a very low level as compared to the products and hence, energy is supplied to overcome this difference.

Hence, The energy levels of products are <u>higher</u> than the energy level of reactant.

Hence, already stated, heat is required by the reaction and thus heat is written to the reactant side which is to the <u>left</u> side of the equation.

Why do we use only a very small flame to heat the Thiele tube when determining the melting point of a crystalline solid?
Strike441 [17]

The Thiele tube which is look like a triangle, used for the determination of melting and boiling point of the solid and liquid sample respectively. The tube consists of high viscous oil. The mouth of the triangle tube consists the thermometer and the sample through a rubber stopper. The tube is always heated in low flame as the heating mechanism of the oil is through convection current process, in which the molecules of the oil heated passes through out the bulk to make a uniform heat of the liquid. The uniform heat of the liquid is necessary to determine the exact melting point of the solid. Also the low heating rate is compulsory so that the rate of convection current be slow. The high heating rate may cause fast convection in the oil and the hot oil can spill out from the tube and may cause an accident.
