Which substance will require more energy to heat if all the samples have the same mass? a chart with two columns and nine rows. the first column's header is substance. the second column's header is specific heat j divided by (g times degrees celsius) first row: substance—lead; specific heat—0.129. second row: substance—tin; specific heat—0.21. third row: substance—silver; specific heat—0.235. fourth row: substance—iron; specific heat—0.449. fifth row: substance—calcium; specific heat—0.647. sixth row: substance—granite; specific heat—0.803. seventh row: substance—aluminum; specific heat—0.897. eighth row: substance—magnesium; specific heat—1.023. lead magnesium iron aluminum

Here we have to identify the sample which need more energy to heat the sample 1 degree Celsius.

Among the given elements magnesium will require more energy than the others to heat.

As per the definition of specific heat of a compound, the amount of heat required to increase the temperature of the material 1 degree Celsius is the specific heat of the material.

The given data are-

substance              specific heat

Lead                            0.129

Tin                                0.21

Silver                            0.235

Iron                              0.449

Calcium                        0.647

Granite                         0.803

Aluminium                   0.897

Magnesium                  1.023

From the given data lead, magnesium, iron and aluminium have the specific heat 0.129, 1.023, 0.449 and 0.897 respectively. Thus magnesium will require more energy than the others to heat.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
