A 15.75-9 piece has a specific heat of 0.46 J/g °C, and its temperature changes from 25°C to 175°C. How much energy does it absorb?

Q = 1086.75 [J]

Explanation:

We must use the following equation of thermal energy, which relates the specific heat to the mass and to the change in temperature.

Where:

m = mass = 15.75 [g]

Cp = specific heat = 0.46 [J/g*C]

Tfinal = final temperature = 175 [°C]

Tinitial = initial temperature = 25 [°C]

Now replacing:

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

the rearrangement of particles in a physical change. hope this
