The specific heat of ice is about 2 J/g◦C while for liquid water the specific heat is about 4 J/g◦C. The energy required to raise the temperature of 10 g of ice from −5 to −4◦C is ___________ the energy required to raise the temperature of 10 g of liquid water from +4 to +5◦C. 1. greater than 2. less than 3. the same as

Respuesta :

Answer:2) less than

Explanation:

Given

specific heat of ice[tex](c_{ice})=2 J/g^{\circ}[/tex]

specific of water[tex](c_{water})=4 J/g^{\circ}[/tex]

energy required to raise the temperature of 10 g of ice from [tex]-5 to -4 ^{\circ}[/tex]

[tex]E_1=m\times c_{ice}\times \Delta T[/tex]

[tex]E_1=10\times 2\times 1=20 J[/tex]

For water

[tex]E_2=m_{water}\times c_{ice}\times \Delta T[/tex]

[tex]E_2=10\times 4\times 1=40 J[/tex]

Thus [tex]E_2> E_1[/tex]
