Korolek [52]

Answer: speed up food processing

speed up plant growth

Increase fuel efficiency

Explanation:

A catalyst simply refers to a substance that leads to an increase in the reaction rate when it's added to a substance. When the activation energy is reduced by catalysts, this.hwlpa on the speeding up of a reaction.

Therefore,the functions of catalysts include speed up food processing, speeding up plant growth and increase fuel efficiency

A rigid canister with a radius of 5 in and a height of 10 in is filled with air. The initial pressure and temperature of air in
Elza [17]

Answer:1.458 Btu

Explanation:

Given

radius of canister\left ( r\right )=5in

Height of canister\left ( h\right )=10 in.

Initial pressure\left ( P_i\right )=14.7 Psi

Initia ltemprature\left ( T_i\right )=70^{\circ}F

Final pressure\left ( P_f\right )=30Psi

as canister is rigid therefore change in volume is zero

therefore

\frac{P_i}{T_i}=\frac{P_f}{T_f}

\frac{14.7}{70}=\frac{30}{T_f}

T_f=142.85^{\circ}F

volume of canister=\pi \times r^{2}\times h

                               =\pi \times 5^{2}\times 10=250\pi

volume of canister=12872,038.8 mm^3

now calculating mass of air

PV=mRT

substituting values

\left ( 14.7Psi\right )\left ( 12872,038.8 mm^3\right )=m\left ( 0.287\right )\left ( 70^{\circ}F\right )

m=21.0192 gm

Therefore heat transferred =mc_p\left ( T_f-T_i\right )

                                             =21.0192\times 10^{-3}\times \left ( 142.857-70\right )

                                             =1539.052J=1.458Btu
