Question

what is the specific heat capacity of water?
select one:

6.02×10²³ j/g·°c
1.00 cal/g·°c
4.18 j
0.46 j/g·°c

Explanation:

Specific heat capacity is the amount of heat per unit mass required to raise the temperature by one degree Celsius. For water, it is defined as \(1.00\ cal/g\cdot^{\circ}C\). \(6.02\times 10^{23}\) is Avogadro's number, not related to water's specific heat. \(4.18\ J\) is the conversion factor between calories and joules (\(1\ cal = 4.18\ J\)), but not the specific heat capacity value. \(0.46\ J/g\cdot^{\circ}C\) is incorrect for water.

Answer:

1.00 cal/g·°C
