N: 60 mol
p: 20 atm = 20×1013hPa = 20260 hPa
T: 50°C = 323 K
R: 83,14 hPa·dm³/mol·K
V: ?
.................
pV = nRT
V = nRT/p
V = (60×83,14×323)/20260
V = 79,529 dm³ ≈ 79,6 dm³
79,6 dm³ = 79,6 L

Answer:
Radiation
Conduction
Convection
Explanation:
<u>Radiation:</u> Transfer of heat by electromagnetic rays (Example: A microwave heating food)
<u>Conduction:</u> Transfer of heat energy from one object to another through direct contact (Example: Getting out of bed and your warm feet touch cold tile, making the tile warm and your feet cold)
<u>Convection:</u> Movement of heat by a fluid such as air or water (Example: A convectional oven works by heating the air inside the oven to evenly cook food)
