Burt's mother asked him to use a spoon to stir the stew that was cooking on the stove. Which spoon will stay the coolest while h

e stirs and why?
Question 9 options:

An aluminum spoon because it can only be heated by radiation.


An iron spoon because it is a strong conductor of heat.


A wooden spoon because it is an insulator.


A silver spoon because it is an insulator.

Metals are good conductors of heat and electricity

Metals are good conductors due to presence of free electrons

They act as carrier to conduct heat or electricity.

So

Aluminum spoon will heat up as it is of metal

Iron spoon will heat up as it is of metal

Silver spoon will also heat up as it is of metal

Wood is a bad conductor of heat. It is an insulator

Wood has air space or pockets in its structure which makes it a bad conductor (it cannot conduct heat)

So a wooden spoon will be stay coolest as it is an insulator

Car wax mostly contains beeswax and carnauba wax. These large hydrocarbons are ideal to use because they _____ water.
hichkok12 [17]
These waxes are highly hydrophobic (repellant) of water, so the correct answer would be D) repel.

The wax coating put on the car creates a water repellant sheila that causes the water to bead up on the surface of the wax, rather than directly impacting the paint and surface of the body of the car. This prolongs the life and quality of the appearance of the car.

A 32.5 g iron rod, initially at 22.4 ∘C, is submerged into an unknown mass of water at 63.0 ∘C, in an insulated container. The f
Allisa [31]

Answer:

The mass of water m_{w} = 39.18 gm

Explanation:

Mass of iron m_{iron} = 32.5 gm

Initial temperature of iron T_{1} = 22.4°c = 295.4 K

Specific heat of iron  C_{iron} = 0.448 \frac{KJ}{kg K}

Mass of water = m_{w}

Specific heat of water  C_{w} = 4.2 \frac{KJ}{kg  K}

Initial temperature of water T_{2} = 336 K  

Final temperature after equilibrium T_{f} = 59.7°c = 332.7 K

When iron rod is submerged into water then

Heat lost by water  = Heat gain by iron rod

m_{w} C_{w} (T_{2} - T_{f} ) =  m_{iron} C_{iron} ( T_{f} - T_{1} )

Put all the values in above formula we get

m_{w} × 4.2 × ( 336 - 332.7 ) = 32.5 × 0.448 × ( 332.7 - 295.4 )

m_{w} = 39.18 gm

Therefore the mass of water m_{w} = 39.18 gm
