Answer:
Explanation:
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.
Answer:
Its B Nylon
Explanation:
i just took the quiz and got it right.
Answer:
The answer to your question is Q = 18702.5 J
Explanation:
Data
mass of water = m = 447 g
Cp = 4.184 J/g°C
Temperature 1 = T1 = 25°C
Temperature 2 = T2 = 35°C
Heat = Q = ? Joules
Process
1.- Write the formula to calculate heat
Q = mCp(T2 - T1)
2.- Substitution
Q = (447)(4.184)(35 - 25)
3.- Simplification
Q = (447)(4.184)(10)
4.- Result
Q = 18702.5 J
Answer:
Their average kinetic energy increases
Explanation:
The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.
Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.
- As the water in the pot heats up.
- The rice gains thermal energy.
- This causes the molecules of the rice particles to start vibrating.
- As the molecules vibrate about their fixed position, their thermal energy continues to increase.
- Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.
Answer:
Hydrogen Bond
Explanation:
Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.
In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.
