Find the final equilibrium temperature when 10.0 g of milk at 10. c is added to 1.60 x 10^2g of coffee with a temperature of 90.
IRINA_888 [86]
The concept that can be used in order to answer this item is that of the conservation of heat among the system. We let T be equal to the final temperature. The equation that would allow us to relate the initial and final conditions of both substances is as follows,

     m₁cp₁(T - T₁)  = m₂cp₂(T₂ - T)

The first entity, 1, is the milk and the second entity, 2, is the coffee. We are given that the specific heats of both substances are just equal so we can eliminate them from the equation. Substituting the known values,

   (10 g)(T - 10°) = (1.60 x 10^2 g)(90° - T)

The value of T from the equation is 85.29°C.

Answer: 85.29°C

What is the mass of a cube of aluminum that is 4.0 cm on each edge? The density of aluminum is 2.7 g/cm3. Show all calculations
Naddika [18.5K]
The mass is

Explanation:
First, we need to find the volume of the cube.
v = lwh
v = (4)(4)(4)
v = 64 cubic cm

Now, since we know the volume and the density, we can figure out the mass.

The formula is mass = volume x density
Mass = 64 x 2.7
Mass = 172.8 g.

Therefore, the mass is 172.8 grams.

A sample of an ideal gas has a volume of 2.31 l at 287 k and 1.10 atm. calculate the pressure when the volume is 1.45 l and the
balu736 [363]
Hello!

The pressure of the Ideal Gas when the volume is 1,45 L and the temperature is 298 K is 1,82 atm.

To solve this problem we need to apply the Ideal Gas Law for the initial conditions and the final ones, clearing the equation for the number of moles (n) and the ideal gas constant (R) which remain constant:

P_n*V_n=n*R*T_n \\ \\ n*R= \frac{P_n*V_n}{T_n}

Now we match n*R for the initial conditions (1) and the final ones (2), clearing the equation for P₂

\frac{P_1*V_1}{T_1}= \frac{P_2*V_2}{T_2} \\ \\ P_2= \frac{P_1*V_1*T_2}{T_1*V_2}= \frac{1,10 atm*2,31 L *298 K}{287K*1,45 L}=1,82 atm

Have a nice day!
