Question

comparing specific heat of different materials
material | specific heat (j/g°c)
aluminum | 0.90
iron | 0.44
lead | 0.16
sand | 0.83
steel | 0.49
wood | 1.80
water | 4.18
use this chart showing the different specific heat of various materials to answer the questions.
which material has the highest specific heat? lead
which material has the lowest specific heat?
which material has the ability to absorb twice as much heat as aluminum when placed in the same environment of mass and temperature?

Explanation:

Step1: Identify highest specific heat

Check the specific heat values: aluminum (0.90), iron (0.44), lead (0.16), sand (0.83), steel (0.49), wood (1.80), water (4.18). Water has 4.18, the highest. The initial dropdown for highest was incorrect (lead is low), correct is water.

Step2: Identify lowest specific heat

Among the values, lead has 0.16, the lowest.

Step3: Find material with twice aluminum's specific heat

Aluminum's specific heat is 0.90. Twice that is \( 2\times0.90 = 1.80 \). Wood has 1.80, so wood.

Answer:

1. Highest specific heat: water (correcting the initial wrong dropdown; water has 4.18 J/g°C)
2. Lowest specific heat: lead (0.16 J/g°C)
3. Material with twice aluminum's heat absorption: wood (1.80 J/g°C, which is \( 2\times0.90 \))
