Answer:

Non metals are brittle solids.

Explanation:

The option A is correct,

Non metals are brittle solids.

It is the property of non metals. They can not be stretched into thin wire if stress is applied non metals brake down.

All other options are incorrect because,

B = Non metals are often malleable

It is the property of metals. Metals can be malleable into think sheets.

C = Non metals often conduct electricity.

It is the property of metals. Metals conduct electricity because of availability of free electrons.

D =  Non metals are often ductile.

It is the property of metals. They can stretched into thin wire.

1. An electric power plant uses energy from burning coal to generate steam at 450 °C. The plant is cooled by 20 °C water
kap26 [50]

Answer:

Explanation:

Efficiency of the electric power plant is e=1-\frac{T_{2}}{T_{1}}

Here Temperature of hot source T_{1} = 450^{o}C=450+273=723 K

and Temperature of sink T_{1} = 20^{o}C=20+273=293 K

Hence the efficiency is  e=1-\frac{293}{723}=0.5947=59.47%

Now another formula for thermal efficiency Is

e_{therm}=\frac{Q_{1}-Q_{2}}{Q_{1}}=\frac{W}{Q_{1}}

Here QI is the of heat taken from source 100 MJ ; Q2 of heat transferred to the sink (river) to be found

W is the of work done and W = QI -Q2

Hence Frome_{therm}=\frac{Q_{1}-Q_{2}}{Q_{1}}=\frac{W}{Q_{1}}

W=e(Q_{1})=(0.5947)(100)=59.47MJ

Hence the of heat transferred to the river Is Q_{2} -W = (100 -59.47=40.53
