Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0°C. (a) Find the gauge pressure, in standard atmospheres, inside such a bulb when it is hot, assuming its average temperature is 60.5°C and neglecting any change in volume due to thermal expansion. (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the glass bulb will expand a small amount. What will the actual final gauge pressure be, in standard atmospheres, assuming the thermal coefficient of volume expansion is 2.7 x 10$°C?

Can you help me with this? I need the answer for number 1

A mectal cylinder of 5 cm in diameter and initially at a temperature about 150 °C. the eylinder is suddenly immersed in liquid with temperature at 50 °C and heat transfer coeflicient about 2000 W/m.°C. Under typical operation conditions the center temperature and surface temperature are measured to be 110 °C and 90 °C after 1 minute, respectivielly. Calculate the thermal conductivity for this material.

please help on the below question.....not that there are 2 imagies
