Answer:
gamma rays only is the correct answer.
Explanation:
Every radiation has different penetrating power to penetrate in materials and the flow of particles through a material is called penetration power.
Penetrating power of the gamma rays is very high because it has no mass and charges that the reason it can travel far in the air than beta particles and alpha particles.
Alpha particles can be blocked by paper and beta particles can easily passes through paper but it cannot pass through aluminum sheet whereas gamma particles are hardest to blocked, gamma particles can be blocked by heavy shielding.
Thus the radiation can pass through sheet of metak and hit the target is only gamma rays.
All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.
<h3>What is Endothermic reaction?</h3>
Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.
In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.
Therefore, All of the energy from the reactants will be lost to the surroundings.
The energy found in the reactants remains in the system, and the reactants also take energy from the
surroundings is true of energy in reactants during endothermic reaction.

Answer:
3.5 g
Explanation:
The density of water is 1 g/mL. The mass (m) corresponding to 20.0 mL is 20.0 g.
We can calculate the heat (Q) required to raise the temperature of 20.0 mL of water 1 °C (ΔT).
Q = c × m × ΔT = 1 cal/g.°C × 20.0 g × 1 °C = 20 cal
where,
c is the specific heat capacity of water
There are 160 calories in 28 g of Cheetos. The mass that releases 20 cal is:
20 cal × (28 g/160 cal) = 3.5 g
