Find the number of 1-foot cubes that fill the fish tank
<h3><u>Explanation;</u></h3>
Volume of a cuboid such as the fish tank is given by the product of length width and height;
Such that; Volume = length × width × height
Similarly, we can count the number of 1 foot cube that can fill the fish tank.
And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.
<span>Answer:
Q= mcâ†T
Q = energy (heat) generated or absorbed
m = mass of the substance undergoing the change in temperature
c = specific heat of the substance undergoing the change in temperature
â†T = T(final) - T(initial)
We are given:
m = (25.0 mL + 50.0 mL)*(1.00 g/mL) = 75.0 g
c = 4.18 J g^-1 °C^-1
â†T = 33.9 °C - 25.0 °C = 8.9 °C
Now we just plug those numbers in:
Q= mcâ†T
Q = (75.0 g)*(4.18 J g^-1 °C^-1)*(8.9 °C)
Q = 2790.15 J = 2.79 kJ (to three sig figs)</span>
Answer:
Conditions to Avoid: Natural gas is extremely flammable and explosive; avoid heat, sparks, open flames, and all possible sources of ignition. Heat will increase pressure in containers used to store natural gas.Jun 1, 2015
