°F = (9/5)°C + 32.
Therefore from this we can say that slope of line drawn for graph between temperature in °C & °F is 9/5 = 1.8.

For measuring temperature in a thermometer we need a substance whose physical properties change with temperature and can be easily related with temperature. Mercury’s volume increases linearly with increase in temperature and hence we can create a scale on the thermometer accordingly.

Temperature in K = 273 + temp in °C.
∴ Temp in °C = 300-273 = 27
°F = (9/5) °C + 32
= (9/5)*27 + 32
= 80.6°F.

ABomb calorimeter works at constant volume, so it is isochoric in nature. Here, the heat energy that’s measured is only the internal energy. The work done is zero because of no change in volume.

In a Bomb calorimeter, the reaction occurs in a vessel and that is surrounded by the water bath. If it is an exothermic reaction the temperature rises and if it is an endothermic reaction the temperature decreases. Temperature can be measured using a thermometer.

The latent heat of vaporization of water is 2260 KJ/Kg. The heat that is required to convert water at 373 k to steam is given by Q = mL, where m = mass of the water and L = latent heat vaporization of water; heat energy required = 1 kg x 2260 KJ/Kg = 2260 KJ.

Proteins are heteropolymers made of amino acid monomers. There are 21 amino acids. Various numbers and combinations of amino acids in a sequence or chain forms different types of proteins.

Structure of molecules in inorganic chemistry refers to the molecular formula of the compound. In organic chemistry it refers to the two-dimensional structure while in physics it refers to the three-dimensional structure.

In physics, the structure of molecules refers to the three-dimensional structure of the molecule. In inorganic chemistry it refers to the molecular formula of the compound. In organic chemistry it refers to the two-dimensional structure.

There are four levels of structural organization of proteins. These are the primary structure, secondary structure, tertiary structure and the quaternary structure. The level affects the function of the protein.
