Una fábrica que se dedica a la producción de cilindros que contienen gas propano (H3C‐
CH2‐CH3), con una capacidad de 30 lbs., los cuales están almacenados en un cuarto
oscuro a una temperatura de 25 ºC. En la noche un corto circuito provoca un incremento
de temperatura de 25 ºC hasta 500 ºC en el cuarto oscuro. Todos los cilindros se
encuentran con sus llaves de seguridad cerradas.
 ¿Qué crees que les ha sucedido a las partículas contenidas en el cilindro por el
efecto de la temperatura?
a. La velocidad de las partículas del gas disminuye, pero aumentan sus choques
contra las paredes.
b. La velocidad de las partículas aumenta, pero el número de choques entre ellas
permanece igual
c. La velocidad de las partículas aumenta al igual que el número de choques
contra las paredes
d. d. Las partículas aumentan su tamaño a causa del incremento de la
temperatura

Plz me ! 1 which of earths spheres contains most of its mass? a atmosphere b hydrosphere c geosphere* d biosphere 2 erosion and weathering are examples of which types of forces? a constructive forces b destructive forces* c gravitational forces d inertia-related forces 3 which of the following statements about earths atmosphere is true? a earths atmosphere contains 78% water vapor which is essentail to life b earths atmosphere contains 21% oxygen c earths atmosphere contains carbon dioxide which all life forms require d earths atmosphere allows radiation from the sun to pass through it and warm earths surface* 4 the strenght of the force of gravity between two objects is determined by which of the following factors? select all that apply a the messes of the objects* b the distance between the objects* c the volumes of the objects d the surface area of the objects 5 earth and moon are kept in there respective orbits due to the influence of a inertia b gravity c gravity and inertia* d neither gravity or inertia if you answer all questions right i will give

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
