Which solid object has the highest specific heat? -aluminum -silver -wood -ice

2 answers:

6 0

The aluminum's temperature changed less than the copper's did under the same conditions. Thus, the aluminum must require more energy to change its temperature. Therefore, aluminum has the higher specific heat.

Answer:

Aluminum

Explanation:

Because aluminum temperature changed less than the copper's did under the same condition. This, the aluminum must require more energy to change its temperature

makvit [3.9K]

Answer:

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.

cooling a sample of matter from 70°c to 10°c at constant pressure causes its volume to decrease from 873.6 to 712.6 cm3. classif

jek_recluse [69]

Explanation:

Expression for the coefficient of thermal expansion is as follows.

$\alpha = \frac{1}{V}(\frac{\Delta V}{\Delta T})$

where, V = initial volume

$\Delta V$ = Final volume - initial volume

= (712.6 - 873.6) $cm^{3}$

= -161 $cm^{3}$

Now, we will calculate the change in temperature as follows.

$\Delta T$ = Final temperature - Initial temperature

= (10 + 273) K - (70 + 273) K

= 283 K - 343 K

= -60 K

Substituting these values into the equation as follows.

$\alpha = \frac{1}{873.6} \times (\frac{161}{60}) K^{-1}$

= 0.00307 $K^{-1}$

It is known that for non-ideal gases the value of alpha is 0.366% which is 0.00366 per Kelvin. As it is close to our result, hence the given sample of gas is a non-ideal gas.

Does 1.0 M KNO3 or 1.5 M KNO3 have a higher boiling point?

jasenka [17]

1.5 M KNO3 - both solutions contain KNO3, but the one with higher concentration is 1.5 M, as 1.5 M > 1.0 M. 1.0 M also increases the boiling point, but not to as great an extent as 1.5 M does.
