Answer:
a substance that dissolves in another substance
Explanation:
a substance into which another substance dissolves
Explanation:
When a large block of ice is placed in a hot cup of water then some of the ice will melt into the cup. As a result, when ice melts then after sometime temperature of cup will become equal to the temperature of ice.
Therefore, ice won't melt further as surface area of cup is small so, only some of the ice will melt into it.
Whereas when same block melts when dropped into a lake it completely melts because lake has large surface area and hence, ice will melt into it easily. This is also because there is different in temperature of both ice and lake.
So, ice will melt into it as temperature of ice will be less than the temperature of lake.
Answer:
Sand has less specific heat than water.
Explanation:
Specific Heat is amount of heat needed per unit mass, to raise temperature by 1 degree celsius.
More specific heat means more heat energy needed to increase temperature. It implies - more time needed to absorb heat, increase temperature; and also more time needed to lose its heat.
Less specific heat means less heat energy needed to increase temperature. It implies - less time needed to absorb heat, increase temperature; and also less time needed to lose its heat.
Sand has less specific heat than water. So, it needs less heat absorption to increase temperature by per unit (celsius) ; than water. Hence, same level of heat to both sand & water ; increase temperature of sand more than water, & make it more hot.
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a <span>large dipole moment. However, because one dipole points to the left and the other to the right the dipole is cancelled.</span>
Answer:
Human sometimes also anerobically respite this happen usually during vigorous exercise when our heat and lungs are not able to supply enough oxygen to muscle and they carry out anaerobic respiration
