Answer:
You missed the specific heat on water, that is 1 calorie/gram °C. This answer is, 0.12°C
Explanation:
The stayment says, that all of the energy from the pancake is transferred into the water, so we have to think that 61 calories are burned in the calorimeter with water. Let's apply on the formula.
Heat added = specific heat x mass x (tfinal - tinitial)
61 cal = 500. g .1 cal/g °C . ΔT
61 cal / 500 g / 1 cal/g °C =ΔT
0.12 °C = ΔT
Answer:
B
Explanation:
When the sun shines evenly on Earth, both hemispheres are experiencing either fall or spring.
Earth orbits the Sun counterclockwise and in position A the southern hemisphere is experiencing summer, so if the options are in order, the southern hemisphere is experiencing spring in position B.
... I didn't see the picture when I wrote this answer, I still got it right though!
Well yes but its another form of weathering so true
Answer:
They are each made of matter. Some are compounds made of one type of element. Some are pure atoms.
Explanation:
Matter refers to the particle which has inertia and takes up physical space. As per modern physics, the matter is made up of different types of particulates, each with its mass and size. elements are consist of only one type of atom and can exist as either atoms or molecules whereas compound is incorporated of two or more different elements that are bound together, chemically. As per the question silver is an element while others are examples of compounds and they both belong to the category of matter.
A - the paper can be burned
this is irreversible
being irreversible is a chemical property
