What quantity of heat is required to raise the temperature of 460g of aluminum from 15C to 85C?

Chemistry

Hoochie [10]4 years ago

Answer:

Q = 28.9 kJ

Explanation:

Given that,

Mass of Aluminium, m = 460 g

Initial temperature, T_i=15^{\circ} C

Final temperature, T_f=85^{\circ}

We know that the specific heat of Aluminium is 0.9 J/g°C. The heat required to raise the temperature is given by :

Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\Q=460\ g\times 0.9\ J/g^{\circ} C\times (85-15)^{\circ} C\\\\Q=28980\ J\\\\\text{or}\\\\Q=28.9\ kJ

So, 28.9 kJ of heat is required to raise the temperature.

Water is made of polar molecules, and oil is made of nonpolar molecules. Based on your observations, which molecules attract eac
victus00 [196]

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.

<h3>What are polar and non-polar molecules?</h3>

Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.

Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.

Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

Which correctly summarizes the trend in electron affinity?
ra1l [238]

The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
