Answer:
The plate would only begin to slowly cool down
Explanation:
As the plate is introduced to room temperature the plate kind of stimulates oxidation in a way as in the plate is no longer in a state of continuous heat.
Test tubes heat small amounts of liquids while boiling tube boils liquids

Answer:Methane(CH4) and dioxygen(O2) are the reactants
Carbon dioxide(CO2) and water(H2O) are the products
Explanation:
The first step to answering this item is to convert the given temperatures in °F to °C through the equation,
°C = (°F - 32)(5/9)
initial temperature: 72°F
°C = (72 - 32)(5/9) = 22.22°C
final temperature: 145°F
°C = (145 - 32)(5/9) = 62.78°C
Substituting to the equation,
H = mcpdT
H = (43 g)(0.903 J/g°C)(62.78 - 22.22)
H = 1574.82 J
<em>Answer: 1574.82 J</em>
