Answer:

A, D and E.

Explanation:

When two systems with different temperatures are in contact, they try to achieve thermal stability, which occurs when they have the same temperature. To this happens, heat must flow from the system with a higher temperature for the other.

So, the heat must flow from warm water to the vegetables. But there is a plastic bag between then, it must conduct that heat to the vegetables.

The water loses an amount of heat, and the vegetables gained the same amount of heat.

Heat is transferred from water to the vegetables.

When the vegetables receive heat, it changes the kinetic energy of its molecules: they start to vibrate faster, which makes the temperature increase.

The water is losing heat, so it's cooling down.

Which mixture can be separated based on differences in the particle size of the components?
Rina8888 [55]

Answer: Mixtures you can separate are like cereal and milk. Hope that helps

Explanation:  Filteration is required to separate a mixture.

So heterogeneous mixures (that contain substances with different particle sizes)  can be separated with a filter.  

Homogeneous mixtures are uniform in composition so they will not be able to be separated.

Typically, your percent yield is ______ than 100% because ___________________________.
masya89 [10]

Reasons why percent yield is more than 100

Typically, percent yields are understandably less than 100% because of the reasons indicated earlier. However, percent yields greater than 100% are possible if the measured product of the reaction contains impurities that cause its mass to be greater than it actually would be if the product was pure.
