Answer:
The energy will be flowing from hot coffee to ice cube. The energy flow will stop when both temperatures of coffee and ice cube will become equal.
Explanation:
The second law of thermodynamics deals with the direction in which spontaneous processes go. Many processes run spontaneously in one direction, that is, they are irreversible under certain conditions. Although irreversibility is seen in everyday life, for example, a broken glass does not return to its original state, complete irreversibility is a statistical statement that cannot be seen during the life of the universe. More specifically, an irreversible process is a process that depends on the route. If the process can only go in one direction, the reverse path is fundamentally different and the process can't be reversible. For example, heat always involves the transfer of energy from a higher temperature to a lower temperature. A cold object that comes in contact with a hot object never cools, transfers heat to the hot object, and heats it up.
X volume= 2x2x2=8
y volume= 8x8x8=512
512/8=64 so you can fit 64
Answer:
Their must be a picture with this question so we can answer it
Explanation:
Rate of Sulfur dioxide : 2730.44 mL/s
<h3>Further explanation </h3>
Graham's law: <em>the rate of effusion of a gas is inversely proportional to the square root of its molar masses or </em>
the effusion rates of two gases = the square root of the inverse of their molar masses:
![\rm \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac%7Br_1%7D%7Br_2%7D%3D%5Csqrt%7B%5Cdfrac%7BM_2%7D%7BM_1%7D%20%7D)
or
![\rm M_1\times r_1^2=M_2\times r_2^2](https://tex.z-dn.net/?f=%5Crm%20M_1%5Ctimes%20r_1%5E2%3DM_2%5Ctimes%20r_2%5E2)
MW of N₂ = 28 g/mol
MW SO₂ = 64 g/mol
![\tt 28\times 79^2=64\times r_2^2\\\\r_2^2=\dfrac{28\times 79^2}{64}=2730.44~mL/s](https://tex.z-dn.net/?f=%5Ctt%2028%5Ctimes%2079%5E2%3D64%5Ctimes%20r_2%5E2%5C%5C%5C%5Cr_2%5E2%3D%5Cdfrac%7B28%5Ctimes%2079%5E2%7D%7B64%7D%3D2730.44~mL%2Fs)
Chemical energy is in the Pontential Energy group....Maybe?
