yes because thermal energy is heat which can also be radiation

sample response:

No, thermal energy is not being transferred by radiation in this image. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.

3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the

eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$$R = \frac{V}{I}$

Now we have to plug in the values as,

$$ R = \frac{150}{2.34}$

= 64.1 Ω

So the resistance of the appliance is 64.1 Ω.

Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other h

aleksandrvk [35]

Answer:

Concentration = 1.32 m

Boiling point = $83.44^{0}C$

Explanation:

Let the boiling point of two solutions = T

Let the molal concentration of the two solutions= m

The relation between elevation in boiling point and molal concentration is:

$elevationinboiling point=K_{b}Xmolality$

i) For benzene

$T-80.1=2.53Xm$

$T=2.53m+80.1$ ....(1)

ii) For carbon tetrachloride

$T-76.8=5.03Xm$

$T=5.03Xm+76.8$ ...(2)

Equating the two equations:

$5.03Xm+76.8=2.53m+80.1\\m=1.32molal$

Putting value of "m" in equation "1"

$T=2.53(1.32)+80.1=83.44^{0}C$
