Interpretation:
The use of fire blanket needs to be explained.
Concept introduction:
Rapid oxidation of materials in exothermic reaction during combustion is known as fire. It releases heat, light and other reaction products. There are different ways to extinguish the fire. One must be familiar with the safety equipment in the lab. Before participating in any chemistry activity, one must know where the safety equipment is kept so that in case of any emergency one can easily reach out to them, likewater, fire extinguisher cylinders, etc. are used in case of fire but there are few drawbacks of these substances.
Explanation of Solution
The fire can be extinguished by breaking its contact with air because air contains oxygen which promotes the fire. Latest device to control fire is use of fire blanket. It is a soft fire controlling device. It has following advantages likeenvironment friendly, easy to carry as well as easy storage. Best property is that it is a good insulator and high-temperature resistance device. It can be used everywhere like kitchen, hotels, garage, and gas station as well as in laboratory, etc. and it is only used to extinguish small fires.
Basically, anything catches fire in presence of air/oxygen known as combustible substance so to control/extinguish fire, onemust cut the contact of air.

- The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1arrow_forwardDon't used Ai solutionarrow_forwardIn an experiment, the viscosity of water was measured at different temperatures and the table was constructed from the data obtained. a) Calculate the activation energy of viscous flow (kJ/mol). b) Calculate the viscosity at 30°C.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
