A sample of an unknown substance has a mass of 0.465 kg. If 3,000.0 J of heat is required to heat the substance from 50.0°C to 100.0°C, what is the specific heat of the substance?
Use q equals m C subscript p Delta T..
0.00775 J/(gi°C)
0.0600 J/(gi°C)
0.129 J/(gi°C)
0.155 J/(gi°C)

0.129J(gioc)

Explanation:

The basic formula for specific heat is Q=MC∆t, where m is the mass, C is the specific heat, and ∆t is the change in temperature.

The parameters given are Q= 3000j = 3kj, mass is 0.465 and ∆t is (100-50)= T2-T1

By imputing them we have;

Q=MC∆T

30= 0.465xCx(100-50)

3=23.25C

C= 3/23.25

=0.129J(gioC

you will find groups such as germans, acadians, irish/scots, french, spanish, anglo/americans, african americans, and native americans. you are looking for the contributions that each of these groups provided to the settlement of louisiana.

answer: it is true that students often work and do household chores, but managing homework in addition to other responsibilities students learn to organize their time efficiently and prioritize their studies.

the first argument attacks those who disagree, asking them to be "realistic" and "accept facts." this is not conducive to healthy debate and disagreement. the second one only takes into account a section of the student population, and ignores the other one. finally, the third option offers only anecdotal evidence. it is only the last option that provides a well-constructed argument in a persuasive way.
