Answer 1

What amount of heat is required to raise the temperature of 20 grams of water from 10C to 30C? The specific heat of water is 4.18 J/gC.

Answer 2

1200 joules
1500 joules
1700 joules
1900 joules
2000 joules

Answer 3

\[\sf Q= mc \Delta T\]

Answer 4

You have all the needed values
\[\sf \Delta T\] is temperature change = Final temp - Initial temp

Answer 5

im confused @Somy

Answer 6

What amount of heat is required
Heat required = symbol in this formula is Q
to raise the temperature of
20 grams = mass
of water
from 10C to 30C? = is Temperature change Delta T

The specific heat of water is 4.18 J/gC. = the symbol is C and this value is constant for water

Answer 7

SO WHAT SHOULD I DO ?

Answer 8

@Somy

Answer 9

put the values into the formula and get the answer, wasn't that obvious? x.x

Answer 10

Q=MC Delta T. Therefore 4.18 (C- specific heat capacity) * 20 (Delta T- Change in temp) * 20
