Question

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

Answer 1

Answer:2) less than

Step-by-step explanation:

Given

specific heat of ice
`(c_(ice))=2 J/g^(\circ)`

specific of water
`(c_(water))=4 J/g^(\circ)`

energy required to raise the temperature of 10 g of ice from
`-5 to -4 ^(\circ)`

`E_1=m* c_(ice)* \Delta T`

`E_1=10* 2* 1=20 J`

For water

`E_2=m_(water)* c_(ice)* \Delta T`

`E_2=10* 4* 1=40 J`

Thus
`E_2> E_1`
