The temperature change in water is 9.95°. The temperature change in methanol is 20.65°. Water removes the thermal energy from the engine better.

<h3>What is a cooling system?</h3>

A cooling system is a system that is design to reduce the temperature of a car engine as the car in in operation.

For water;

H = mcθ

H = heat added

m = mass of water

c = heat capacity of water

θ = temperature rise

θ = H/mc

θ = 836.0 ×  10^3 J/20 Kg × 4200

θ =  9.95°

For methanol;

mass = density × volume = 0.80 g/cm3 × 20000cm^3 = 16Kg

Hence;

θ =  836.0 ×  10^3 J/16Kg × 2530J

θ = 20.65°

The thermal energy that is removed is higher with water.

Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.
Nuetrik [128]
Wow ! This question reads like it might have come from one of
Faraday or Maxwell's original laboratory notebooks.

Choice-A is the correct one, when you consider what "conductance"
means. Conductance is just 1/resistance .

So when you see
"A) Current is proportionate to the conductance of the circuit and
precisely proportional to the voltage applied across the circuit."

what it's saying is
"Current is inversely proportional to the resistance of the circuit, and
directly proportional to the voltage applied across the circuit."

If you write the equation for all those words, it looks like

I = V / R

and that's correct.

Lily took 6 hours to complete a journey at an average speed of 58 km/h. For the first 4 hours, she travelled at an average speed
disa [49]

Answer:

92 km

Explanation:

Total distance = 6 x 58 = 348 km

Distance travelled in first 4 hours

= 4 x 64

= 256 km

Distance for rest of journey = 348 - 256 = 92 km

That's because helium molecules are not packed together as densely as air molecules are. It is this simple reason that helium ba
Zinaida [17]

Answer:

Because the molecules are not packed together as much than the air, in a fixed volume of helium there are fewer particles than in the same fixed volume of air.

This means that the mass of the fixed volume of helium is smaller than the one of air, and then the density, defined as mass/volume, is also smaller.

This is why the balloon floats, because the air is denser, it tries to go down, pushing the ballon upside.

The case is similar for a piece of metal in water, as the metal is way denser than the water, the metal will sink, but for something not as dense, like a balloon with air, the balloon will remain in the surface of the water.
