Answer:

Explanation:

Comment

You could calculate it out by assuming the same starting temperature for each substance. (You have to assume that the substances do start at the same temperature anyway).

That's like shooting 12 with 2 dice. It can be done, but aiming for a more common number is a better idea.

Same with this question.

You should just develop a rule.  The rule will look like this

The greater the heat capacity the (higher or lower) the change in temperature.

The greater the heat capacity the lower the change in temperature

That's not your question. You want to know which substance will have the greatest temperature change given their heat capacities.

Answer

lead. It has the smallest heat capacity and therefore it's temperature change will be the greatest.

Find the relationship

\\ \rm\Rrightarrow Q=mc\Delta T

\\ \rm\Rrightarrow 100=10c\Delta T

\\ \rm\Rrightarrow 10=c\Delta T

\\ \rm\Rrightarrow \dfrac{10}{c}=\Delta T

\\ \rm\Rrightarrow \Delta T\propto \dfrac{1}{c}

So lower the c higher ∆T

Lead has the largest change in T as it has least capacity

How many liters are in 0.034 moles of chlorine gas?
Anuta_ua [19.1K]

The volume of the gas is 7.6\cdot 10^{-4}m^3

Explanation:

At standard temperature and pressure (stp), the volume occupied by 1 mole of an ideal gas is always equal to

V=22.4 L

In this problem, we have an amount of moles of gas of

n = 0.034 mol

Since 1 mol of gas occupies a volume of 22.4 L, we can set up the following ratio:

\frac{1 mol}{22.4 L}=\frac{0.034 mol}{V}

where V is the volume occupied by 0.034 mol of gas. Solving for V, we find

V=\frac{0.034 mol}{1 mol}(22.4 L)=0.76 L

Or, in cubic metres,

V=0.76 L = 7.6\cdot 10^{-4}m^3

A radio signal takes 1.28 s to travel from a transmitter on the Moon to the surface of Earth. The radio waves travel at 3.00108
yulyashka [42]

Answer:

s = 3.84 x 10⁸ m

Explanation:

The distance traveled by an object, while in uniform motion, is given by the following equation:

s = vt

where,

s = distance covered

v = speed

t = time interval

In this case:

s = distance between Moon and Earth = ?

v = speed of radio waves = 3 x 10⁸ m/s

t = time taken to travel = 1.28 s

Therefore,

s = (3 x 10⁸ m/s)(1.28 s)

<u>s = 3.84 x 10⁸ m</u>

Unit of work is derived unit why​
adoni [48]

The unit for work J can also be written as Nm. Therefore, it is a derived unit as different SI units are needed to obtain its value. In this case, its derived from force and distance.
