Answer:
Heat will flow from the air in the container into the cube.
Explanation:
Heat flows from<em> places with higher</em> temperature to <em>places with lower </em>temperature.
With that information in mind then we can see that the cube of copper has a lower temperature than the air in the container (85°C > 5°C), thus heat will flow into the cube.
Answer:
Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.
Explanation:
We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.
Answer:
24000
Explanation:
Given that:
The numbers of carbon atoms = 8000
According to the Einstein model of solid;
Einstein’s model assumes that each atom of the solid vibrates around its position of equilibrium independently of the other atoms (which amounts to neglecting the interactions between particles.
Number of oscillators = 3(8000)
Number of oscillators = 24000
Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
