You are trying to heat up a cup of water with a butane lighter.

algol13

Answer:

Step-by-step explanation:

Remark

The formula for this is

Heat = m * c * Δt

Givens

Heat = unknown

m = 200 grams

c = 4.184 Joules / grams oC

Δt = the change in temperature = 35.7 - 22.3 = 13.4

Solution

Heat = 200 * 4.184 * 13.4

Heat = 11213 Joules

Heat = 11.2 Kj

It's hard to get the correct number of sig digs because the 200 is not qualified in any way.

Part 2.

This can really puzzle you until you know that heat given up = the heat taken on. The heat taken on was 11.2 Kj. The Butane lighter must have given that heat on.

Heat of Combustion = Heat Given Up / Number grams burned.

Heat of Combustion = 11.2 Kj / 0.23 grams

Heat of Combustion = 48.8 Kj / gram

Please help been stuck on this for 40 minutes

choli [55]

we have given y interms of x.

we have given that add 2 to x.

which means $y=x+2$

so we have $x=2 ,y=x+2=2+2=4$ .

so when x $=2 ,y=4$ .

$x=4,y=x+4=4+2=6.$ .

$y=x+2,y=6+2=8$ .
