If the specific heat of iron =0.46j/g celsius how much heat is needed to warm 50 g of iron from 20 degrees celsius to 100 degrees celsius

Heat energy required to raise the temperature of iron will be given as

here we know that

m = 50 g

s = 0.46 J/g C

now we will have

so it will require 1840 J heat to raise the temperature

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
