The amount of heat energy added to silver to heat it from 25°C to 100°C is :
8737.5 J
<u>Given data: </u>
mass of silver ( m ) = 500 g
T1 = 25°C
T2 = 100°C
s ( specific heat of silver ) = 0.233 J/g.c
<h3 /><h3>Determine the amount of heat required </h3>
Applying the formula below for heat ( Q )
Q = ms * ΔT
= 500 * 0.233 * ( 100 - 25 )
= 8737.5 J
Hence we can conclude that the The amount of heat energy added to silver to heat it from 25°C to 100°C is : 8737.5 J.

Answer: The bond formed between the elements will be ionic bond.
Explanation: We are given two elements having electronic configurations:
Element 1: 
Element 2: 
Element 1 can easily loose 1 electron to attain stable electronic configuration and Element 2 can accept 1 electron to attain stable electronic configuration.
For these elements, there will be a complete transfer of electron from Element 1 to Element 2. Hence, this will form a ionic bond.
From the configuration, Element 1 is Lithium and Element 2 is Fluoride. So, the compound is LiF.
The pressure in a sealed container means the volume of container is fixed
so we cannot change the volume of container hence gas
The other factors which can affect the pressure are
a) moles of gas : if we increase the moles of gas the pressure of gas will increase
b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy
So the following cannot increase pressure
a) decrease in moles of gas
b) decrease in temperature of gas
