Answer:
Stimulus
Explanation:
Any change in an organism's environment that causes the organism to react. It is a scientific way of saying “cause”. Example: An animal is cold so it moves into the sun. Response: how the organism reacts to a stimulus and results in a change in behavior.

Answer:
1. Students need to measure masses of the items.
2. Put baking soda and vinegar in a plastic bag and close it.
3. Mix the two, allowing for a reaction to occur.
4. Figure the mass of the plastic bag while the two components are inside.
5. The combined mass should be equal to what each weighed on their own.
Explanation:
Answer:
c = 0.07 j/g.k
Explanation:
Given data:
Mass of sample = 35 g
Heat absorbed = 48 j
Initial temperature = 293 K
Final temperature = 313 K
Specific heat of substance = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = Final temperature - initial temperature
ΔT = 313 k - 293 K
ΔT = 20 k
Now we will put the values in formula.
48 j = 35 g × c× 20 k
48 j = 700 g.k ×c
c = 48 j/700 g.k
c = 0.07 j/g.k
