Four beakers have water at 27 °c. a piece of metal is dropped into the water in each beaker. the table below shows the initial temperature of the four metals. a - 30 degrees c b - 42 degrees c c - 25 degrees c d - 16 degrees c which metals will transfer heat to the water? a. metals a and metals b b. metals b and metals c c. metals c and metals d d. metals b and metals d

Answer

A. Metals A and metals B

Explanation

Heat transfer takes place whenever there is temperature difference. When two bodies of different temperatures are brought together, heat energy will move from one body to the other until equilibrium temperature is reached.

In our case, heat transfer will take place in all four metals.

Metal A will transfer heat to the water since it's temperature is higher than that of water.

Metal B will also transfer heat to the water since it's temperature is higher than that of water.

Metal C will get heat from the water since it's colder than the water.

Metal D will also get heat from the water since it is colder than water.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
