Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.
<h3>What is an Exothermic Reaction ?</h3>
When a chemical reaction happens, energy is transferred to or from the surroundings.
When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.
ΔH value negative –> energy released –> exothermic reaction
This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.
The energy diagram for the exothermic reaction is attached with this answer.

Answer:
Explanation:
1.Scientists use a shared system for reporting measurements called the International System of Units (SI). We use common measurement systems because science involves a lot of replication to confirm results. The most common system used in science is the metric system.
2.m, kg, m^3
3. g value change

Answer:
1 dm
Explanation:
Centimeter and decimeter both are units of length.
Centimeter is represented as "cm" while decimeter is represented as "dm"
centimeter is larger than decimeter. One centimeter have 10 decimeter.
1 cm = 10 dm
So in order to convert cm to dm we will divide the given value by 10.
10 dm × 1 cm/10 cm
1 dm
Answer:
The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up.
